Where did you get that formula from? Wiki has it listed as:
CODE
Spell damage multiplier = 1 + prof / 200
If using wiki's formula, shouldn't your equation be 1 + (38.62% x 1) + 264/200 = 1 + .3862 + 1.32 = 2.7062? You could be right though since you are more experienced, but I'm just going with what was posted on wiki.
wiki's formula is only referring to the proficiency factor.
The total magic damage is: (damage roll)(1+rating/100)(1+EDM/100)(1+MDM/100)(1+prof/200)
Since gear(expect staff) doesn't provide rating and MDM, so you can "eliminate" that.
