Big Bang Level EXP Curve

Shouldn't # of hits to kill be regarded more than total amount of damage?

33000 kills @ 1-3 hits to KO becomes 20000 kills @ 3 hits to KO (or 2 hits in the 1 in 400 chance both times crit)

I don't have exact numbers on the rates I do 1hko, 2hko, 3hko currently though, so I'm not sure whether that's an improvement or not (my range is 35000-95000 atm, something like 110000-117000 after bb, on targets with 85000 hp now vs. 260000 after bb)
