Proc rate normalization
This hasn't changed recently, has it? Every proc that reads "on hostile spell this will cast X 1.8 times per minute" is still a 9% chance to actually cast the proc on the item, due to 3 second spell normalization?
Formula: Actual Chance % = (Cast time/3) * Displayed %
To calculate displayed percent, take procs per minute (1.8), normalize to 3 sec cast spells, so in one minute you cast 20 spells:
1.8/20 = 9%
so for this example, with 3 sec cast: 3/3*9% = 9%
, with 2 sec cast: 2/3*9% = 6%
, with 1.5 sec cast: 1.5/3*9% = 4.5%
Or has this changed? Thx for help in advance.
