Obi, booking losing sessions should not be too hard. When it's time, just quit a session, even if it's 10 minutes after you say down and you were down only $50. A losing session is a losing session whether you lose $50 off $5k. We often turn a losing session into a winning session by sticking around for a longer session. If you make a decision to play 40 minutes, just play 40 minutes.
