For me it all depends on the Bankroll.
Cash game for example:
Set a Limit of minimal rebuys you still want to have. Like lets say 10 times 2NL so 20 bucks. now you win and go to lets say 30 bucks. You can invest 10 bucks in 5NL if you keep winning and go to 10 times 5 plus 10 times two you can go to the next Limit. If for some reason you start losing you just go back one Limit whenever you dont have your minimal Rebuys left.
That Way you can always play, always improve, always win and never risk too much of your Bankroll to not be able to come back.
I hope you can understand what I wnat to say.
