After 1000+ tournaments I think that the variance shakes out.
You have good stats but if you were playing under 5.00 and are now playing 50.00+ tournaments your numbers are going to get crushed (along with your bankroll).
That is simply too big of a jump. I think you should go the next 3 months in the 5-10.00 range and see how you do.
Despite what you see on TV, the best players in the world are people you never heard of who play exclusively online. Playing 50-100.00 is pretty exhausting and doing it day in and out is something you really need to make sure you have that skill set.
