Good luck Langaan, hope you reach your goals!

Similar to the 40bb/100 discussion.

If you can infact maintain that winrate, then what is the trigger to moving up to 50nl?

Try to think about hourly as much as winrate. Just because your winrate drops, doesn't mean your hourly well. (ie: playing more tables or higher stakes, with a lower winrate, but higher hourly rate).

Good luck! I hope you're right about the winrate stuff!
