Acc formula

[sleekmotorwurkz]

I tried this in the "random question" thread and got no real info so I guess Ill give this a shot maybe people just dont hit the stickys...

random question....

How is the acc calculation done on the melee accuracy checker?
Melee Accuracy Calculator
It seems to be somewhat broke. acc still calculates right, but hit% is stuck at 95% So I was thinking of making a small little app for myself to do different calculations. Add in stuff like marinara pizza, and other mobs besides the standard ones you can select from...

I know
dex/2 (or dex*8/10 for 2h) is added in the acc

weapon skill level is something like 1 point up to a certain lvl then .9 after? right?

Mob's eva vs your acc? How does lvl difference get taken into account.

And what would be the best way to figure out if giving up x haste for y acc is worthwhile?

Acc for 1hand is (Dex/2) + (skill 200 or lower) + (.9 x every skill over 200) + gear. 2hand I believe is (Dex x .75) + the rest is the same

As for that calc, I don't think all of its mobs are accurate. I happened to be passing through the mire last night otw to ejar so, I wanted to test the imps. The lv 80 imps were said to have 314 evasion and the lv 81 imps were reported to have 320 evasion. I went in with 292 skill, 71 based dex, and 0 gear, which comes up to 317-318 depending on how you play with decimals, and every imp I checked while running through there still checked as low evasion.

Could be spawning lower lvl.

Ah, wiki reports the imps in the mire to be 80-81 range and I was able to check a good 5-6 of em, which is why I believed that info to be incorrect.

1. 95% is the hard cap.

2. There's a ton of variables to factor in making it quite hard to calculate. Main job, sub job, target mobs, attack, all available buffs, food obviously. It's not as clear cut as haste vs acc. Just merit different setups and parse the results.

I know 95% is the hard cap but whether I have 100 total acc or 400 total acc the number isnt changing off 95%
I know on average the magic number is around 415 but im trying to figure out how all the variables are added up to equal that 415, and how that 415 compared to the mob's eva/level to get 95%.

For the haste vs acc question I was thinking more like...
if you add in x accuracy it leads to a certain % hit rate
where as
if you add in x haste it leads to increased amount of hits. And with slightly less accuracy, adding in these many more hits with say 92% accuracy is the same as 95% accuracy and having this many hits -> and finding where the 2 lines cross.

[WraithLakshmi]

Hit Rate = 75% + (Accuracy - Evasion) x 0.5% + (Attackers Level - Defenders Level) x 2

How to compare Accuracy to Haste:

1. Calculate Hit rate with and without the accuracy piece. Divide your hit rate with the accuracy by your hit rate without accuracy. This will give you your increase to melee DPS.

2. For haste, (1 - (haste without haste piece)) / (1- (haste with haste piece)). This will give your increase to melee DPS for haste. Make sure to include things like Hasso, Haste spell, or march if you usually have a bard singing it for you.

3. Compare the two, whichever is larger wins.

And Sleek, to thank me for being so awesome and bestowing my knowledge upon you, you have to shout in Whitegate for 5 minutes, "Wraith is my hero, he is soo sexy and smart."

DoT = damagePerRound * HitRate / HasteCoefficient

Given that, you can calculate the trade off margin between accuracy and haste.

Assuming damagePerRound is the same, then you're comparing these 2 number
X1 = HitRate / (HasteCoefficient-dHaste) <- setup with more haste
X2 = (HitRate + dHitRate) / HasteCoefficient <- setup with more accuracy

Say with Ace's you have 95% hit rate exactly, so using Turban it'll put you on 91.5% hit rate.
Buff from outside is 35% (double march, haste spell) and your gear have 17% haste on Turban
X1 = .915/(1 -.52) = 1.90625
X2 = .95/( 1- .51) = 1.93876

Ace's helm is better by 1.93876/1.90625 = ~1.7%

something like that.
