Ok, the problem is that I get 30/20/8 (vpip, pfr, 3bet) stats on NL50, even though on every other speed limit (well, lower limits, haven't played NL100) I get 21/17/5 or something (and that's how I've played all my life, and these are correct). Also other players (regs) have very loose stats like me on NL50, but on other limits they have tighter stats.
I'm 100% convinced there is something going on, either on iPoker or my HEM.
