I was wondering what people's thoughts were on what the actual number of hands played at a certain level should be before moving up? If someone flies through any given level after running hot, should they move up just because they're rolled for it? or should they wait until they've played x number of hands(20k for example)?

I recently took a shot at 100NL 6max with the idea that I'd move back down if I lost 3 buy-ins. After losing those buy-ins and taking a look back, I really feel like I was outplayed by the few decent players that I've been up against.

This all came after I ran real hot basically from the time I first took shots at 50NL FR and 6max.

So the question is, should I just build the BR back to where I'm comfortable to take shots again, or should I sit back for a number of hands and really analize my game? Also, if this was a different level would, the answer be different? I assume they would be.
