Ø All data is for REKO. But, the strategy does not make a huge difference. Better strategies can allow slightly higher betting without increasing risk.
Ø All calculations assume optimal betting ramps, perfect play, and a $10,000 bankroll. If you halve the bankroll, you must halve the bets.
Ø The numbers in the cells are the minimum and maximum bet allowed. For example, if the game is 6D, S17, DAS, 5/6, the bet spread is 1-12, and the desired risk of ruin is 10%, then you can bet $11 to $132. Your unit size is $11. You will note that dropping the bet in half can dramatically drop the risk.
Ø Obviously no one is going to bet odd numbers like $132. Numbers are provided to the dollar for accuracy, but can be rounded with little effect.
