So I recently moved to 25NL (yet again) after moving through 10NL w/o much trouble (yet again) at like 13BB/100 after ~ 13,000 hands. Well it's been about 9,000 hands at 25NL so far and I am down a little over 3 buy-ins. I've heard that after about 10,000 hands you can see if you are beating the game or not. I've basically been an aggressive nut straddler. My play hasn't changed that I am aware of. I don't go broke w/ TPTK. My biggest losing hands so far have been...

- flopped top 2 vs. straight - board of QT8 rainbow
- losing to T2 w/ my AJ (top pair w/ the A) - villain called my bets whole way and caught a 2 on the river for trips.
- losing to K7 w/ AQ - villain called w/ middle pair (7's) and caught a K on river
- middle set over top set
- getting AI w/ maniac PF w/ AQ vs. his KQ
- flopping low straight out of BB w/ 63 and losing to flopped higher straight
- calling psb's to river w/ 15 outer and having to fold
- flopping top 2 w/ T7 out of BB and losing to flopped set of 3's on rainbow board
- betting whole way w/ top 2 and losing to villain's runner runner flush
- baby flush vs. higher flush

any advice from anybody? i beat 10NL very easily and i did have some rough downswings so it's not like i had an upswing for 13,000 hands. i've tried the move to 25NL in the past and i've been greeted with this same kind of crap each time. i do not care that it is more money on the table either so i'm not playing scared and my bankroll is large enough. have i just not played enough hands? i'd appreciate any advice.
