How to calculate accuracy?
So I'm just wondering if its better a +15% accuracy food or a +15 one, but I cannot get it if I dont know my base accuracy. Is there any way to calculate it?

accuracy = weapon skill lvl + (DEX/2) (plus starting accuracy. what you have when you have 0 dex and 0 skill)

this assumes that weapon skill level adds to accuracy in the same way it adds to attack. this also assumes that DEX acts on accuracy in the same way STR acts on attack and VIT acts on DEF

There are two misconceptions here.

1.) DEX/2 is not an accurate equation for accuracy. I don't feel like digging up the interview or the countless other posts on this forum or other forums with genuine parses that prove this to not be true, but that this has been covered. DEX->Acc and AGI->Racc are non-linear relationships.

2.) Accuracy+15% does not mean you figure out what your quantifiable accuracy number is (say... 100+52) then multiply by 1.15. It means you hit the mob ~15% more often, until you hit the cap. So if you normally hit for 60%, eating accuracy+15% food means you'll hit roughly 75% of the time. It never quite works out that perfectly, but that's the jist of it.

Unless you were perhaps lv.1, accuracy+15% should always yield greater results than accuracy+15.

square should clarify this once and for all

i mean, when i buy a game i can tolerate that there are hidden secrets like hidden weapons and hidden areas, but not clarifiying what the info on your stats means is too much, thats like allowing you to write, but not allowing you to learn how to -.-

1) as far as i know, this is unknown. the interview only says it's more beneficial to raise accuracy by raising it directly, not that DEX-> acc isn't a linear relationship. and since the formula of acc stat -> hit % is, to my knowledge, unknown, as well as the effects of DEX on hit %(independant of accuracy stat), i don't believe this has been proven, or even come close to it.

2) that would explain how they got the information.... i was wondering how they could identify the effects of the food as accuracy + 15% without knowing the formulas for accuracy.
but, how do you know? can you point us to where this is stated?

Mithrael is correct in both regards.
This was listed in the latest official guide Vana'diel World Report.
Very nice and detailed list of food and effects etc in this 700 page brick.

I never knew a resource like this existed, is there an English version available, or in the works?

1.) I won't bother because it can never be "proven." There has been plenty of work to demonstrate that DEX does not have a 2:1 relationship to accuracy. There is great difficult in proving anything with a random component though. For example, adding dex increases your critical rate. Since critical attacks can never miss, your accuracy is increased through a side channel. In any case, your formula, whether the dex part is right or not is extremely suspect. Another reason for this is that each point of weapon proficiency adds something closer to .7 accuracy instead of 1. again, you can dig up the posts if you want more confirmation of this.

2.) I parse all of my exp and merit parties. it's very clear when you parse yourself over the course of month what each food effect does for you.

is that +.7% hit percentage, or +.7 accuracy stat? or are they the same thing?

can you look them up please? i can't seem to find them.

i found this thread, which gives some insight into the matter.
and this thread, which says what i said, except has an extra formula for lvls 61-75.
but i can't find anything that supports what you said (and i can't read that book either).

.7 accuracy, since clearly, once your weapon proficiency is greater than 142 you'd exceed 100% accuracy if it were .7%, which is impossible. Biggok's Data (look at his equations) assume .9 accuracy per level of weapon proficiency.

I'll just have to concede to you. I can't find the posts, and the search function of this board is nigh useless since you can't search for anything under 4 letters. I seem to recall most of the ones supporting the <1:1 relation of skill to accuracy involved Rugal. DEX<->Accuracy has been hased out many places, trying to find it is difficult since every abbreviates DEX and Acc instead of Dexterity and Accuracy. Anyway, I have no intention at the moment to level an alternate job, and my DRK is already 75... so, that pretty much dissolves any support for my argument.

I will say flat out that I believe there is an error in the thinking of many of the equations that people come up with for things in FFXI. They almost never include a basis for your level vs. the mob level. If you fight any mob that cons IT, then fight it again and it cons VT, your accuracy improves immediately, even before your weapon proficiency caps again. Another example is how hard PLD74 get hit vs. PLD75 in dynamis, or against Sky Gods, etc.

Consider for a moment how you're able to hit mobs at lv.1 with relative frequency before you even have weapon proficiency. How does that compare to once you're lv.10, lv.20, lv.30, lv.40, lv.59? Does a lv.24 Mithra THF/NIN DEX36+18 (102 accuracy with capped dagger) have the same hit rate as an unequipped lv.30 THF/NIN with DEX43 using a sword? (103 accuracy)? What if the mob is easy prey to both of them? What if the mob is lv.30 (IT to the lv.24 and EM to the lv.30)? They may both con "Low Evasion" but can the lv.24 really hit the IT mob as often as the lv.30? My guess is no.

Actually Mithrael, I believe Apple Pie informed me that there is a 1:1 correlation between weapon proficiency and weapon accuracy for levels ... 1-60 I think. It might be 1-50, but I can't remember. I'm in the same boat as yourself, it's hard digging up the old threads where I used to talk about this due to the sheer abundance of threads talking about DEX or ACC. I'm pretty sure Apple Pie stated that at the higher levels (61+ I suppose), each level of weapon proficiency added the equivalent of 0.9 accuracy.

I have nothing to prove this except from what Apple Pie told me, and I believe he got it from a japanese resource. I didn't test this stuff personally, so take it with a grain of salt.

As for what Mithrael said about DEX + ACC relationship, I agree... it is not a direct correlation. I can attest to this from different experiments I performed with various equipment setups (all parsed) ... but then again, even then much of the experimentation is hard to deem foolproof since there will always be a variable I can't easily control (monster level/type/etc).



I believe in karma. Anyone I treat badly probably deserved it.

I wouldn't know about that, if there are a ton of American's that's FF "phr33ks" I still don't think it compares to how many japanese FF "phr33ks" there are out there hehe.

As for the books, there really isn't any company that's dedicated enough to go into full detail on most of the books. I mean I haven't even seen the m00k book for this game, but knowing how the japanese are, their books are insanely detailed and are hundreds of pages longer than what we see here. Now, getting it translated, I don't know why most companies won't, but it's either the company that created it doesn't wanna sell it to the American companies, or maybe because the American companies would rather create one for their own.
