Moving up a level should be in direct correlation with:
1. Your bankroll
2. Your game level (skill, mental)
3. Your game plan to move up/down when you should.
pretty much what he said, even after like 1 million hands, you can determine your winrate to only about +- 0.75bb/100, and since u have to consider your game changes all the time, its absolutely impossible to determine your true winrate...
50k hands should give you a basic insight of how are u doing and if ur really beating the limit though...
as to moving up, i think for NL2/5/10/20 it is enough to take shots with 20bi's, but u have to be disciplined enough to move down as soon as you fail the shot...
but that really depends on you a your comfortability only... if u dont feel comfortablee enough, than go and take shots with 50bi's... if u feel like taking it with 20bi's then by all means, go for it!
wouldnt go lower than 20 though, it might prove disasterous
