Comfortability, short and sweet.

If you're playing decent in your own mind and are winning decently over a few thousand hands, then move up. If you don't think you're good enough for $0.50/$1, post a few hands of say $0.25/$0.50 in the Stud section and see if you're just unlucky for those few trivial hands or are generally playing bad. If you get positive responses, then move up. I don't think there is or ever will be a set winrate or money won over x amount of hours to say you need to move up. You cannot and should not move up unless you feel comfortable doing so. You can crush 50NL for $1K in a day, but if you don't feel comfortable playing against the 100/200NL players, then you shouldn't move up.
