I think your bankroll is the best indicator. If the bankroll grows, it obviously means that you are doing everything right.

Well thats not a complete answer.

Your bankroll must grow constantly for a long period of time. Also you must have understanding of what is going on and why. I mean some beter player from higher limits should not break your game by coming at your table, making you question all you know about poker.
So if you play some limit for a long time and your bankroll keep growing no matter what, then you can beat this limit.

I would say that after 100,000 hands at a given game, you will begin to see some convergence.
