I have a different conception of psychological bankroll that an author, perhaps Schoonmaker introduced. Traditonal bankroll requirements are supposed to insulate you from the risk of going broke. Plug in win rate and standard deviation and you come up with something in the neighborhood of 300 BB. However, psychological bankroll is how much you can lose before it starts to affect your play. For instance you may determine that a 400 BB bankroll makes it virtually impossible for you to go broke if you play your normal best game. But you could still be in jeopardy if when you lose 100 BB you start to steam or go on tilt.
