My suggestion is to have it scheduled when you're going to look at your tracker to check up on your stats and make sure you're not going past whatever bankroll guidelines you have and to make sure you're also not picking up any bad habits. I'd personally suggest once a week for people who are playing < 10k hands a week and twice a week, say Wednesday night and Saturday night, for people playing > 10k hands/week or so.

Congrats to everyone who made it.
