My first 10k hands where I really concentrated, and treated this like its for real, I was about where you are, roughly 3.5 BB/100. I thought great, this is easy! I got my bankroll up and moved up a level, and started right off and am currently in a -100BB swing at my new level. So now, I'm wondering if I was just lucky, if the play at this level is that much better (i'm very very confident that's not it), or if I'm just having a bad run of cards. I think its a little bit of everything, leaving me w/ no real answer as to where I stand. So yeah, play alot more hands for a few more months and see where you're at, you'll have a much better idea.
