More comments on the relationship between INT and effective magic accuracy

Last week I got into this "debate" about magic accuracy (BG) regarding the results of casting Stone "a bunch of times" (massive understatement) on Qiqirn Poulterers. After inspecting lodeguy's elemental magic data back in December 2008, I speculated about a model for elemental magic to explain lodeguy's results, not expecting to find any other data to provide independent confirmation for this "model." But thanks to pchan, we now have even more data for which this model agrees (assuming I'm not being irredeemably biased in my perspective) along with some new insights that I describe rather turgidly in one of my posts there.

For example, it is known that the effects of additional magic accuracy, elemental staves, and elemental magic skill appear to be cut in half when "effective" magic accuracy or "hit rate" (the output that depends on the aforementioned inputs) is sitting below 50%. This latest data shows that the effect of INT appears also to be halved below 50% (for ΔINT ≤ 10).

Perhaps more relevant is the observation that, given this data, the effect of INT could be attenuated even further as ΔINT goes further and further beyond 10. That is, it could be (statistically) significantly less than +0.5% "hit rate" for every one-point increase in INT above ΔINT > 10. However, my naive analysis is based on statistical control and not experimental control of levels of INT, the latter of which seems preferable to minimize the influence of potentially confounding factors (as unlikely as they may seem).

Curry buns

Unless RMT are dumping inventory, I don't see why anyone would still craft Coeurl Subs instead of Yellow Curry Buns. From a crafter's standpoint, crafting Yellow Curry Buns will give a slightly better yield on the average because it's only a level 54 recipe ("tier 3" achieved at 105 cooking skill) and the most typical HQ result is 8 buns instead of 6.

But the real nail in the coffin, assuming that it's true, is that the buns retain the hidden bonus of the corresponding curries. Apparently, (hope I'm interpreting this Google translation correctly), the attack cap on Yellow Curry rises to 85 when eaten in the presence of four or more people in the same party as the consumer, among other attribute differences. Amazing that it's 2009 and players still don't know this. (Well, I never used yellow curry so I didn't know.) For Red Curry, the condition is apparently the same, but the attack bonus rises from 23% to 25% (still capped at 150). If the buns retain these hidden bonuses, why wouldn't there be higher demand for Yellow Curry Buns?

Note: the bonus from eating yellow curry (buns) while in a party does not wear off upon leaving the party. Using one while not in a party yields only 75 attack, and it probably does not increase upon joining a party of sufficient size.

The quaintness of dual wielding

It's been almost two years since the pivotal two-handed weapons adjustment, which, among other things, was the beginning of the end for dual-wielding as a mainstream option for warrior.

Before the update, the rates of TP gain and auto-attack damage were generally superior for dual-wielding configurations "most things being equal," as the multi-hit properties of Joyeuse and Ridill amply compensated for lower native sword skill and 8 axe/8 sword seemed to be a popular merit option anyway, leaving no room for great axe merits.

There does not seem to be any simple quantitative comparison of dual-wielding configurations with great axe in terms of rate of TP gain and damage per second, so I did some quick calculations. The following is a "most things being equal" comparison of four canonical dual-wield weapon pairs with Perdu Voulge and Fortitude Axe from the standpoint of auto-attack efficiency, as represented by base damage per second (a modification of the usual "DPS" ratings assigned to weapons per FFXIclopedia accounting for double attack and 95% hit rate) and TP per minute.

Comparison of theoretical auto-attack efficiency of various weapon configurations at 95% hit rate and given 15% double attack rate (no Store TP)

Configuration	Hits/round	Hits/sec	Base DMG/sec	TP/round	TP/min
Maneater/Ridill	2.91175	.4271	18.52	16.01	140.96
Maneater/Joyeuse	2.548375	.3822	15.67	13.76	123.85
Ridill/Joyeuse	3.275125	.5339	20.17	16.37	160.19
Maneater/Iron Ram Pick	2.185	.3013	14.46	12.67	104.88
Perdu Voulge (17% DA)	1.1115	.1323	12.70	15.22	108.76
Fortitude Axe (17% DA)	1.6535225	.1968	12.59	22.65	161.80

All of these values are averages. Base damage per second could be considered a measure of "damage over time" potential. If (average) pDIF and hit rate were held constant across all these options, then Ridill/Joyeuse is the clear choice, which is basically saying if you're farming too-weak mobs. As for rate of TP gain per unit time, which has nothing to do with weapon damage ratings, it was always pretty obvious that axe/sword and Ridill/Joyeuse were more efficient in this respect.

Of course, the aforementioned update eviscerated the normally silly notion of most things being equal as the adjustment brought ample attack and accuracy bonuses (accuracy affecting rate of TP gain when accuracy actually matters, duh!) and Raging Rush was modified to be able to critical hit. Given how parsimonious the "development team" generally was (and is), it was almost unfathomable that the STR-to-attack and DEX-to-accuracy "ratios" were "increased" to 1:1 (from 2:1) before they were scaled down to 4:3.

How about another measure of efficiency, like TP "fed" to a mob per unit time or ratio of damage to TP given to a mob? To the extent that it matters, dual-wielding options were generally worse than great axes (Fortitude Axe aside), which could have been considered an acceptable trade-off back then. But, since the two-handed weapon adjustment really undermined the relative efficiency advantages of dual wielding, the trade-off is not that appealing now for mid-level events like Einherjar or Limbus where you not necessarily be at maximum hit rate. The first floor of Central Temenos is a good example of where dual-wielding would be a complete joke. Again, you didn't have to crunch numbers to have realized that.

Comparison of average TP "fed" to mob per attack round (no attack speed reduction, no Subtle Blow)

Configuration	TP fed/ round	TP fed/ min	Base DMG/ TP fed
Maneater/Ridill	24.75	217.84	5.10
Maneater/Joyeuse	21.40	192.65	4.88
Ridill/Joyeuse	26.20	256.31	4.72
Maneater/Iron Ram Pick	19.22	159.12	5.45
Perdu Voulge (17% DA)	18.56	132.58	5.74
Fortitude Axe (17% DA)	27.61	197.24	3.83

Black mage solo EXP in Xarcabard [S]

This may have gone under the radar for many considering the hype surrounding fay weapons, Igqira Weskits with INT+6 that you'll never get, and the rat race to finish A Moogle Kupo d'Etat (what's the acronym? AMK? MKE?), but this latest version update actually provided an alternative to Ebony Puddings as a solo EXP fodder for level 75 black mages and scholars in the form of the five or so LV 75+ Gigas's Tigers with only 1,400 or so HP within striking distance of the Xarcabard [S] teleport point at (H-9).

Considering the interval between the start of the ToAU expansion and now, this is totally (un)characteristic of SE depending on your point of view, whether you're a fucking retard for fulminating about the "exploiting" the generally low HP of BST pets or a realist.

Perhaps "alternative" is a gross understatement since chain #19 has been achieved on these tiger pets with BLM/SCH (and the attendant MP-efficiency advantages) and the ability to one-shot these tigers with the appropriate weather (ice) or day (Iceday or Lightningday). Not only that, there was the suggestion that these can be chained indefinitely! This seems like a pretty good case for /SCH at this camp if you can one-shot (you have Bind and Sleep anyway).

As for the bread-and-butter /RDM sub, I don't know about you, but even attaining chain #5 on Ebony Puddings (even though I can't three-shot, as in three tier IV), my average EXP/hour doesn't even approach 10K per hour (more like 8K).

In contrast, even without day or weather bonuses and basically lolly-gagging, after trying my hand at these Gigas's Tigers I still managed to average about 8K/hr over two chains with BLM/RDM as summarized in this parser output:

Experience Rates

XP/Hour          : 8039.97

Moreover, after achieving a chain #10 (cheating with Manafont), I averaged over 9.6K/hr on this chain while still not being able to one-shot tigers:

XP/Hour          : 9665.87

I would argue that, at least for me, at worst the EXP/hr in Xarcabard [S] is equivalent to that in Mount Zhayolm, with the potential to clear 10,000 EXP/hr easily with /SCH and enough oomph to one-shot these tigers.

Personally, I would rather not rely on the crutch of having the benefit of the right weather or day effects to be able to one-shot tigers, but my gear or merits do not give me the flexibility to one-shot anytime. After determining that these tigers have 55 INT, I determined that I would need to acquire Selenian Cap with INT+4 and MAB+2, a Novio Earring, and 4 INT merits to clear 1,400 damage with Thunder IV.

With this in mind, those players with Novio and full Morrigan's would have a field day at this camp.

Properties of virtue weapons like Fortitude Axe

Edit (Aug. 5): mixed up scenario labeling but the conclusion is the same.

A few days ago I forwarded these cheesy analyses of the relative "efficiency" of so-called virtue weapons (Fortitude Axe and Love Halberd), which I hope are not taken all that seriously even though I made some attempt to reconcile it with my own experiences or others'. My primary goal with these posts I made over the past week was to demonstrate yet another application of probability theory to simplify such cheesy "analysis" while being somewhat rigorous about it. At least it's better than presenting some ugly arithmetic and retarded hand-waving, as I explicitly stated the major assumptions involved. (But you would have to trust I am doing calculations correctly.)

I bring up the comparisons involving the virtue weapons to point out that I made the assumption that double attack can proc both on the main hit and virtue weapon proc, yielding the possibility of a round of 4 attacks. Actually, I have no basis for assuming such a thing other than flimsy hearsay. With this in mind, I set out to collect data to support the notion that a 4-attack round is possible with Fortitude Axe, and I obtained the following count data after 236 rounds. (I ran out of virtue stones.)

No. of hits	0	1	2	3	4
Counts	5	96	100	35	0
Est. proportion	.0212	.4068	.4237	.1483	.0000

It so happened that I didn't observe a 4-hit round with Fortitude Axe, but is this because it is rare or because it's impossible?

If we assume DA can proc independently of one another for both the initial attack and the virtue weapon proc, the probability of a 4-hit round is .01796 (given 95% hit rate) and the probability that zero 4-hit rounds occur in 236 attempts is .01388. Put another way, the probability that at least one 4-hit round occurs in 236 attempts is .98612.

Thus, if this "mechanism" of interaction between DA and virtue weapons is true, I was unlucky not to see a 4-hit round. But, if it is wrong, not seeing a 4-hit round is exactly what I should expect.

How else would DA and virtue weapons interact such that a 4-attack round is not a possibility?

One scenario, which I call "A," is that there is exactly one DA proc possible and that it's independent of the virtue weapon proc. In this case, DA has only one chance to proc.

Another hypothesis is that whether DA procs on the virtue weapon depends on whether the DA has processed on the initial attack. I call this scenario "B." If DA has processed on the first attack, it will not process after the potential virtue weapon proc; otherwise, DA may process after the virtue weapon swing. In this scenario, there are up to two chances for DA to proc.

Both of these scenarios are not far-fetched, so the question of which one agrees more with the data depends on knowing the hypothetical distribution of number of attacks per round under each scenario given the rate of DA trait and overall hit rate. These distributions are determined for 95% hit rate, 21% DA rate, and 50% virtue weapon proc rate, as shown below.

No. of hits	0	1	2	3	4	Expected value
(A)	.0210	.4235	.4655	.0900	0	1.6245
(B)	.0208	.4162	.4018	.1611	0	1.7033025
(C)	.0208	.4161	.3991	.1460	.0180	1.72425

To summarize, scenario "A" allows DA exactly one opportunity to proc. This DA proc is independent of whether the virtue weapon procs.

Scenario "B" allows DA up to two opportunities to proc. If it procs on the first attack, it won't on the (potential) virtue weapon proc. If it doesn't proc on the first attack, it can on the virtue weapon proc

Scenario "C" allows DA exactly two opportunities to proc (DA and virtue weapons "stack") as explained toward the beginning. The language to describe these may be confusing, but the associated probability distributions are a pretty convenient distillation. Checking the actual data against these hypothetical distributions can give us insight as to which scenario is most reasonable of the three. The "expected value" column shows the average number of attacks per round under each scenario. My initial impression is that (B) seems to be the most realistic.

I already discussed scenario "C." The probability of observing zero 4-hit rounds in 236 attempts is .01388, so scenario "C" is unlikely.

Start with scenario "A." Instead of focusing, say, on comparing the observed proportion of 3-hit rounds to the hypothetical proportions under (A) and (B), it makes more sense to consider all of the data at hand. I can use Pearson's chi-square statistic to examine the "goodness of fit" of the associated probability distribution to the observed data. Under scenario "A," the approximate p-value is .02017, indicating that scenario "A" is not particularly likely given the data.

How about scenario "B" then? The associated p-value is .898 (approximately). Under the scenario that DA is permitted to proc up to two times, the probability of observing count data as "extreme" or more extreme than the data actually observed is about .898, an indication that this mechanism is very plausible.

It bears reminding that in all of these hypothetical cases, I assumed that the virtue weapon proc rate was 50%. This is not necessarily a good assumption. For example the Joyeuse proc rate is more like 45%, contradicting the long-held assumption that it is 50%.

After acknowledging that scenario "B" is the best way to explain my data, it may be useful to see how the probability distributions "shift" by changing the virtue weapon proc rate in increments of 5% in either "direction" of 50%.

Hypothetical probability distributions for the number of hits in a single round, assuming that DA has up to two opportunities to proc on a virtue weapon

Given a virtue weapon proc rate of...	0 hits	1 hits	2 hits	3 hits	p-value
40%	.0246	.4870	.3593	.1289	.08418
45%	.0227	.4516	.3806	.1450	.52411
50%	.0208	.4162	.4018	.1611	.898
55%	.0189	.3808	.4231	.1773	.66298
60%	.0170	.3453	.4443	.1934	.13281

It is easy to see that the probabilities under each column decrease or increase at a constant rate. It is also easy to see what while a virtue weapon proc rate of 50% is highly probable given the data at hand, there is insufficient statistical power to rule out a proc rate as low as 40% or as high as 60%.

Conclusion

Based on an observed sample of 236 attack rounds with Fortitude Axe, it appears that the double attack trait can proc either on the first attack or on the virtue weapon attack, but not both. If it procs on the first attack, it won't on the potential virtue weapon attack. If it doesn't proc on the first attack, it may proc on the potential virtue weapon attack.

The obvious implication is that claims of a four-attack (or four-hit) round with Fortitude Axe and other virtue weapons are highly suspect. If you think you observe a four-attack round with Fortitude Axe or another virtue weapon that cannot be explained by high attack speed, that observation must be considered in the context of the relative frequency of 0-, 1-, 2-, and 3-hit rounds that you probably didn't even bother to record. Idiot.

Also, the proc rate of a virtue weapon might be 50% but there was an insufficient sample size to "prove" it.

A comparison of 5-hit Rindomaru with Hagun

The great katana Rindomaru is one of those new "fey" weapons that can be augmented through the quest "Succor to the Sidhe," and with the possibility that Rindomaru can be augmented with a heap of Store TP, a "5-hit Rindomaru" setup could theoretically rival the boilerplate "6-hit Hagun."

The main comparison here is whether the increased WS frequency from a 5-hit Rindomaru overcomes the Hagun's TP bonus, or whether a hypothetical 25% increase in weapon skill frequency overcomes the 20% increase in weapon skill damage with the TP bonus for the Yukikaze/Gekko/Kasha triumvirate.

A crude calculation of efficency with "most things being equal" could be something like [(88*4+700)/30/(86*5+800)*37.5 - 1]*100 = 6.91%, that is, Rindomaru is more efficient with really crude simplifications. But surely we can be more sophisticated than that.

To start, here is a description of a pretty good augmented Rindomaru (15 Store TP, +4% weapon skill damage, etc.) as well as some specific, full-Usukane equipment setups for both 5-hit Rindomaru and 6-hit Hagun with minor differences, such as Sword Strap for Hagun and White Tathlum for Rindomaru. I will be basing my calculations based on these setups... and the canonical Greater Colibri.

Calculating average time to 100 TP

Weapon	Average no. of rounds	Average no. of hits		Average time (s)
Rindomaru	3.774	4.123		28.310
Hagun	4.690	5.123		34.159

Here, I am assuming 15% double attack rate and 95% hit rate. For Hagun, the reduction of delay is from 450 to 437. Under these conditions, the increase in WS frequency is about 21%.

Calculating average damage to 100 TP (including weapon skill damage)

Weapon	AA "base" damage	WS "base" damage	Average AA damage	Average WS damage	Total damage
Rindomaru	88	167	580.640	709.992	1290.632
Hagun	86	169	705.051	818.463	1523.515

The assumption of using a weapon skill immediately upon getting 100 TP is not all that realistic, but then again all comparisons like this are based on "ideality" and the excuse that this is all supposed to be the case "in the long run." Take the comparison with a brick of salt as you consider the conditions under which it's made.

As another "ideal" assumption, I suppose that pDIF is maxed out for weapon skill damage, and is 1.6 on average in the auto-attack phase. The average number of hits per weapon skill is 1.0925.

How do I account for the "+4% weapon skill damage" on that hypothetical Rindomaru? It sounds like it could be incorporated into the fTP factor. Thus, the fTP factor for the first weapon-skill hit is 1.975 for Hagun and 1.7025 for Rindomaru. For this case, Hagun's average WS damage is about 15% higher.

I also accounted for Meditate but no Overwhelm, mainly because I don't know if Overwhelm affects all hits of a weapon skill.

Damage per second

Weapon	AA proportion of total damage	DPS	Relative efficiency
Rindomaru	.450	45.588	+2.21%
Hagun	.462	44.600	---

Here, you would want to compare the theoretical AA proportion of total damage to what you actually experience.

On paper, this idealized Rindomaru is actually better than Hagun on paper. At this point, you may wonder if using a weapon skill immediately at 100 TP is realistic, so consider also the fairly extreme case of waiting an additional round past 100 TP before WSing (equivalent to starting from 0 TP).

Another comparison of damage per second by "wasting" an attack round beyond 100 TP

Weapon	AA proportion of total damage	DPS	Relative efficiency
Rindomaru	.496	41.286	---
Hagun	.495	41.631	+0.83%

You can think of the last two tables as representing the ideal lower and upper bounds of how fast you WS after attaining 100 TP... in the long run. So if you hold TP, the additional TP will "benefit" Hagun more than Rindomaru and the relative benefit of having a 5-hit setup with Rindomaru is eroded.

Finally, note that this hypothetical Rindomaru has +4% weapon skill damage, which I assumed is an fTP bonus. I consider this the key attribute that allows Rindomaru to eke out a slight edge.

Of course, as far as Greater Colibri are concerned, polearm with attack buffs would be more "fun" as far as cranking out Penta Thrusts with an average easily exceeding 1k. I did manage to find a forum thread with a parse of a 5-hit Tomoe where the AA proportion was about .38.

Comparison of Love Halberd and Tomoe for samurai

I allocated way too much time this weekend to putzing around with spreadsheets, but let's just finish this off, shall we? Here's an example of doing a fairly simple comparison of a 7-hit Love Halberd with a 5-hit Tomoe, which is based on ideas presented in a prior comparison of weapons for warrior. In particular, I utilize the concepts of "expected number of rounds to clear 100 TP" and "expected number of hits to clear 100 TP" to make the arithmetic more tractable.

I didn't see any (good) hypothetical comparison of Tomoe 5-hit versus Love Halberd 7-hit for samurai (using Penta Thrust), so I thought I could do this really fast because I already set up the "black box" (this mess of a spreadsheet) to spit out an answer.

Calculating average time to 100 TP

Weapon	Average no. of rounds	Average no. of hits		Average time (s)
Love Halberd	3.959	6.488		26.131
Tomoe	3.774	4.123		30.197

This is the easiest step as the assumptions are reasonable if idealized, such as 95% hit rate, 15% double attack rate, and starting with some initial TP from the previous weapon skill.

Calculating average damage to 100 TP (including weapon skill damage)

Weapon	AA "base" damage	WS "base" damage	Average AA damage	Average WS damage	Total damage
Love Halberd	70	110	454.179	650.335	1104.515
Tomoe	96	136	395.890	822.614	1218.505

Again, there are more simple assumptions, like using Penta Thrust immediately after attaining 100 TP, using the same fSTR throughout, and assuming an average pDIF of 1. Using the expected values from the previous table, the average auto-attack and WS damage can be calculated.

Also, average WS damage is based on an average return of 5.035 hits.

Did I account for the effect of Meditate? Assuming Meditate recast is 150 seconds, we can assume all the TP goes to one WS and incorporate that damage into one cycle of AA and WS damage. For example, a "Meditate WS" is about 0.174 of a full WS in one cycle for Love Halberd, 0.201 for Tomoe, which makes sense as Meditate will benefit "slower-to-WS" weapons relatively more (Tomoe being slower).

Damage per second

Weapon	AA proportion of total damage	DPS	Relative efficiency
Love Halberd	.411	42.267	+4.75%
Tomoe	.324	40.351	---

Time for a reality check. Is it really possible for Tomoe auto-attack damage to account for only about 33% of total damage? I would have to see some parser output to validate these calculations. If you ignore Meditate, the proportions increase to .451 and .366. I will update this post when I can track down some parser output.

Even accounting for Meditate, Love Halberd comes out ahead on paper by almost 5%. Whether that 5% is worth expending virtue stones in a merit party is another issue altogether. You can't really argue differences in hit rate (if you want hit rate to drop below 95%) since the only real difference would be whatever is used in the ammo slot. As for attack differences, who knows how DEX +7 would compare to attack +5 and whatever's in the ammo slot.

Of course, the major issue, at least to me, is whether DA really stacks with virtue weapons. I've been assuming it does. Even if it doesn't though, Love Halberd is still slightly more efficient.

Cutting corners with Store TP and weapon skills

Edit: Another table appended.

Last week I referred to "minimum store TP" to achieve so-called n-hit builds from the standpoint of going from 0 to 100 TP in n hits or reaching 100 TP in n - 1 hits starting with sufficient TP return from the previous weapon skill, but practically speaking I should have called it "worst-case scenario store TP if you're using a multi-hit WS." With all the TP you'll get after the first hit (and when was the last time you saw only the first hit land when your WS didn't kill your target?), there aren't too many compelling reasons to maintain "true" store TP totals if it means using equipment you wouldn't touch otherwise. The question is how much store TP to drop while still maintaining a "virtual" n-hit.

As you might have guessed, you can turn to probability to answer this. Consider first the case of a 5-hit polearm with a 5-hit weapon skill. After calculating the probabilities for obtaining sufficient TP returns from a single WS (no need to present such clutter, but I hope I didn't screw up), we can see the relationship between dropping store TP and the lowered probability that you will be able to get 100 TP in n - 1 hits of the next TP-generating "cycle." Of course, these probability calculations are based on the assumption that DA can proc only twice on a multi-hit weapon skill (fewer than seven hits).

I am assuming 95% hit rate for the first WS hit. Since (lack of) accuracy does affect TP return, I thought it would be useful to show the effect of a lower hit rate.

Table 1. Probability of getting 100 TP in 4 hits (after a WS) for a 5-hit polearm (480 delay, 17% double attack rate)

Minimum hits after 1st WS hit	Store TP	95% hit rate		80% hit rate
0	54	.95		.95
1	53	.949996		.948865
1	52	.949996		.948865
2	51	.949677		.930353
2	50	.949677		.930353
3	49	.940513		.815681
3	48	.940513		.815681
4	47	.822485		.490462
4	46	.822485		.490462
5	45	.233998		.105841

You can see there is not much of a drop by shedding up to 6 store TP and still being pretty close to a true 5-hit. Remember that the first hit of a WS can still miss.

The probabilities shown are cumulative probabilities in the sense that, given some amount of store TP, what is the probability that I will be able to get 100 TP in 4 hits after a weapon skill? More specifically, given some amount of store TP, what is the least amount of hits I need to land to be able to get 100 TP in 4 hits with an acceptable probability? Remember that .95 is pretty much as good as it gets.

If you have 95% hit rate, 48 store TP gives you a 94% chance of generating 100 TP in 4 hits, requiring at least a 4-hit return from the previous WS (1st hit TP and TP from at least 3 other hits). If you have a "true" 5-hit build, shedding 6 store TP may be a good trade-off. For example, I've seen 5-hit polearm builds with 49 store TP (including merits), suggesting awareness that 54 store TP is rather superfluous.

If you have 80% hit rate, 48 store TP gives you a 82% chance of generating 100 TP in 4 hits, so you might want at least 50 store TP if being around 80% hit rate is more realistic for whatever you are doing.

This exercise can be repeated for both 6-hit polearm and 6-hit great axe.

Table 2. Probability of getting 100 TP in 5 hits (after a WS) for a 6-hit polearm (480 delay, 21% double attack rate)

Minimum hits after 1st WS hit	Store TP	95% hit rate		80% hit rate
0	29	.95		.95
1	28	.949996		.948948
1	27	.949996		.948948
2	26	.949705		.931688
3	25	.941320		.823837
3	24	.941320		.823837
4	23	.832807		.513000
5	22	.284425		.130744

29 store TP not all that easy to obtain as a warrior (maybe you want to use Aurum Cuirass), but 24 is possible with a bunch of ticky-tack pieces. 15 from /SAM, 5 from Rajas, 1 from Brutal, 1 from Chivalrous Chain, 1 from Ecphoria Ring, and 1 from Engetsuto gives 24 total. Then again, if you're spamming crab sushi, some of these may not be very optimal for Penta Thrust.

Table 3. Probability of getting 100 TP in 5 hits (after a WS) for a 6-hit great axe (504 delay, 21% double attack rate)

Minimum hits after 1st WS hit	Store TP	95% hit rate		80% hit rate
0	22	.95		.95
1	21	.948478		.923695
2	20	.889887		.702636
2	19	.889887		.702636
3	18	.034124		.017160

I have only 6 store TP on equipment for warrior anyway. I can live with 21 store TP if I actually am using /SAM for some reason. What about the likes of 6-hit scythe and 6-hit polearm, both with four-hit weapon skills (like Guillotine and Drakesbane)? The following table compares the minimum TP for a "true" 6-hit build to the minimum TP for a "virtual" 6-hit build.

Table 4. Minimum Store TP requirements for 6-hit builds with 4-hit weapon skills

		Minimum Store TP
Delay	Base TP	True	Virtual
528	14.4	16	14
513	13.9	21	18
501	13.6	23	20
492	13.3	26	23
480	13.0	29	26

With "virtual" store TP builds, the corresponding probability is .9449 given 95% hit rate. (Of course, lower hit rate will lower this probability.) If that .0051-difference in probability really troubles you and is unacceptable, by all means be hyper-conservative.

Dumb thread(s) of the day

Here's a new feature where I talk briefly about crappy replies to decent questions. It would be a lot easier just to take pot-shots all day at shitty FFXI forum threads, which I might just do rather than play with numbers all the time.

Apparently, there is a thread on BG discussing why Allakhazam is so maligned, which usually is done by repeatedly knocking down the straw man that anyone actively endorses TPing in STR or DEX rings. When talking about a signal-to-noise ratio, the noise component is rather substantial on Allakhazam but the signal is pretty small in absolute terms for any FFXI forum, really. Even BG has threads like this, where bald-faced assertions are made without referencing sources and people can say they get 8-hit Drakesbanes with a straight face.

As another example, if you were talking about the relative efficiency of a 6-hit polearm build, you would pretty much get the same content-free, inane answers whether you posited this question on Allakhazam or Blue Gartr. Apparently, it is so difficult to use an average auto-attack damage, use an average WS damage, estimate the time between weapon skills, and use all this information to estimate roughly the relative efficiency of a 6-hit build. (Hint: a 6-hit is not even close to being 20% more efficient than a 7-hit). Instead, you have a reasonable OP followed mostly by dumb-fuck snark and drivel.
