Less than 4 hours. If you can multitable and play solid. The higher limit razz games are easy that you'll even be winning with a 9 low sometimes, although I have the tendency to throw it away. Ideally, you want to register into a lot of stuff and reload, then unregister till you get 20K in play chips, then sign into 10 2K play chips STT's, then you can play ring games and higher STT's with that.
