Avoidance Formula's (Theorycrafting)

[PtrN1026]

I was wondering if anyone knows or knows where i can find the formulas used by wow to calculate avoidance (miss/parry/dodge) based on your characters stats. I am working on a spreadsheet that will show how your avoidance changes when you change your stats, but I cannot find clear cut formulas anywhere. I found a page for dodge on Wowwiki but there fairly unclear on what variable is what and what each formula is for. My pre-DR calculations where about 4% off so I know I messed up somewhere.

Any help is greatly appreciated

You could pull it out of the Matlab or Spreadsheet that are sticked in this forum, I suppose. I was going to grab it out of the spreadsheet, but I just found out it's only being published in ODS format now and I have no desire to download open office when Excel is the wider standard. I'll check the m files right fast though.

avoid_dr.m contains all the formulas you'd need. It's written in MATLAB syntax, but it should be pretty easy to understand (.* is multiply, ./ is divide, and the variables are pretty self-explanatory). The notation is taken from this tankspot link, and is pretty standard (k and c for the DR and cap constants).

Thanks for the help and the links, much appreciated.

I have this code I picked up during tBC. I still use it during WoTLK but I think the values have changed and alot of the TC behind it too. I'm looking through the forum at the moment for answers about the avoidance value for 3.2.

Code: Select all

/script DEFAULT_CHAT_FRAME:AddMessage(string.format("Need 102.4 avoidance. Currently: %s",floor((GetDodgeChance()+GetBlockChance()+GetParryChance()+5+(GetCombatRatingBonus(CR_DEFENSE_SKILL)+UnitDefense("Player")-5*UnitLevel("Player"))*0.04)*100)/100))


Enjoy!

Not accurate as it doesn't floor def. (and how often does blizzard not floor calculations srsly?)

Try the one I made at my old guide. Still relevant.
