Hi every1...

Need help with calculations... i've been reading around n around n i'm still not very sure... so hope u guys can help me here...

Defense Rating: 511 - Increase Dodge/Parry/Block by 6.44% & Decrease chance to be hit critically by 6.44%

Dodge: 17.19%
Parry: 17.41%
Block: 20.57%

So... my total avoidance would be: 17.19+17.41+20.57+30=85.17% <-- correct?

If i'm wrong... please let me know how to calculate... thanks.

At first glance, your calculations would seem accurate.

Although, I'm currently enrolled in statistics and would have to say that if you were to perform a critical statistical analysis, your avoidance percentage would actually be lower.

You cannot calculate individual statistics and simply add them together.

For example, if you have 2 samples that have a 20 percent of occuring simultaneously, you would need to perform a choose formula in order to calculate the true rate of occurance. Sorry if it seems complex.

You're really close, the only things you're missing is that defense also decreases chance to be hit, and mobs have a default miss rate of 5%. The best way to get it all is by using a macro:

/script DEFAULT_CHAT_FRAME:AddMessage("Need 102.4 combined avoidance. Currently at:",0.8,0.8,1)
/script DEFAULT_CHAT_FRAME:AddMessage(GetDodgeChance()+GetBlockChance() + GetParryChance() +5+(GetCombatRatingBonus(CR_DEFENSE_SKILL) + 20)*0.04,1,0.5,0)

That will put it right in your chat window.

hmm... thanx for the advice.

the macro however... do i juz blindly copy & paste? or do i hav to add the in figures myself... like below.

/script DEFAULT_CHAT_FRAME:AddMessage("Need 102.4 combined avoidance. Currently at:",0.8,0.8,1)
/script DEFAULT_CHAT_FRAME:AddMessage(GetDodgeChance(17.19%)+GetBlockChance(20.57%) + GetParryChance(17.41%) +5+(GetCombatRatingBonus(370) + 20)*0.04,1,0.5,0)

and also... if i take default miss of 5% and def decrease hit by 6.44%(same as the others) it'd add up to 85.17+5+6.44=96.61% <-- am i there yet? keke

Dodge, Parry, Block, Crit, Crush and Miss are not independant events. This makes it possible to prevent crushing blows.

It is all done on a single roll.

Hah.

Newbie me; I was unaware that a simple macro would take care of your calculation.

Sorry all for being uninformed.

You just copy and paste it into a macro in-game. Cast Holy Shield, then press your macro, and it will tell you how close you are.

96.61% sounds like what you have, but you need 102.4% if you're looking to tank raid bosses. (for tanking 5-mans you should be fine)

Strictly using the "pen and paper" approach and not scripts or macros I like to use the following table:

 
Base Miss = 05.00 %  
Miss      = xx.xx %  
HS        = 30.00 %  
Libram    = 05.33 %  
Dodge     = xx.xx %  
Parry     = xx.xx %  
Block     = xx.xx %  + 
---------------------  
          ( 102.40 ) - 
Total     = xxx.xx %  
=====================  
Short     = xx.xx  %

Where Miss is the number given when mousing over you defense. Remove the Libram is you aren't using the Libram of Repentance.

Sorry if I'm picking on this but just to make it clearer for other readers:

Swisherer was imagining a series of branching choices, eg: roll a dice to see if it's a miss, if it isn't, roll another dice to see if it's a dodge, if it isn't dodged, roll another dice to see if it's a parry etc...

In practice, it's one single roll, and the resulting value is matched against a table: between 0 and 10 it's a miss, between 11 and 22 it's a dodge, 23 and 35 a parry and so on. The table is commonly referred to as the Attack Table, as illustrated in part by Losie's example. When your combined avoidance reaches 102.4% AND you are above 490 defense, there is no room for critical strikes, crushing or normal blows.
