Is S40A included if you buy S40? ALso I bought a system from Ellis a long time ago called the "Asian" which worked real well with choppy shoes with 1-2 neg progression. I could usually win 6-7 units per shoe except in streaky shoes but many times I would bail myself out by just betting on the streak. Isn't this basically the same thing? That is, bet on a randon chop until the shoe proves otherwise then bet on repeats.....
