I'm at a point where i feel like i am beating 10nl with a fairly decent winrate (don't have a sample because i played at a site without handhistories for a while). I'm trying to make a plan to move up to 25nl zoom. How many buy ins would you suggest? I've read a few sources (upswing suggests 100 bi, blackrain suggests 20-40). I've played ~30k hands 10nl zoom on Party. I'm thinking I stay and improve till i have ~60 buy ins, that way i'll have a larger sample and 60 buy ins should be fair right?
