Hey all. Been reading koolmans post about crushing 10NL for 40BB/100 (congrats!) and I'm guessing this is variance, however, over a pretty non massive sample since I've never heard of a win rate that high. I'm wondering though, what a good amount of BB/100 would be to move up and tell that you're truly crushing a level.

First thing to clarify, when people state BBs/100 this means big bets so 2x the big blind right?

I'm currently beating 20NL on i poker for 8BB/100 or 16bb/100 over 14k hands. Am I crushing this level or is it a marginal amount? With all other factors in check, would this be a sufficient win rate to move up with confidence to 50NL?

Thanks in advance for advice on this one.
