I play $100 a unit (1-3 units a game). I use 5-6 books daily( betting and shopping). I like to keep $1,500 ( about 15 units) in each book if I get below 7 units(deposit) or above 40( withdrawal). With weekends I may 25 plays a day I like to start the day with at least (10-15 units in most of my books). When do you guys feel you need to re-up? How many possibile bets in your account is comfortable for you at that book?
