Mob Damage Distribution

I can't tell anymore because critical messes me up. I can see that mobs are less, but I could never give a good estimate because I see such a wide range of numbers I would have to be superhuman to notice any patterns or anything. I also don't remember the low levels because I try my hardest to not pay attention while training.

Fraps your damage on a flat map, crop it to show only you and the damage numbers, then upload it?
Post stats and skill levels, and let the math joars find patterns? Critical is predictable enough to 'undo'.
