for your 2nd rule, "-Lose the first and second bet, then bet 3 units on the third bet. {2,2,3}" ... i think it might be a typo ... should it be: "-Win the first bet and lose the second bet, then bet 3 units on the third bet. {2,2,3}"? (because if you "lose the first and second bet," by your 1st rule, the bets will be {2,3,2}") (i think there were a few betting errors in your first spreadsheet, then) also ... do you mean "if you see a confirmed 3-in-a-row"? ("3 confirmed streaky events" sounds like 3 runs of 4+s, like 454 etc.)
