My current Cash Five program uses "Due Digit Numbers", "Skip Bias Numbers", "Hot Numbers", and "Colder Numbers". I apply the numbers to a Gail Howard wheel that generates 149 picks. I only play blocks of ten numbers, however. My parameters are the history size and block number. I count times that a pick has won something over the last three to ten games. I use parameter sets that have done well in the period that I measured. I have the ability to use day offsets in the history, as well, but I am not using it right now.
