Very very nice stats. I would move up NOW !!
You can only tell so much from stats but I like eveything I see.
I like your $VIP% and I especially like the fact that your individual position $VIP% shows you know to play less hands as you are closer and closer to UTG
One suggestion: Your Won $WSF should be closer to 33$. I suggest that you read my "stealing small pots" article

There wont be much difference in the play at $50NL and your stats prove your ready. Check back in another 10K hands at $50NL and start posting some hands.
