I'm sorry for my bad english. I've been looking for something in numbers for a long time. A few things caught my attention and I tried it. I was able to double my money 27 times. If I were to sample
4 bets: 90:48 incoming number
3 bets: 69.36 incoming numbers
2 bets: 23.93 incoming numbers
1 bet: 66.60 incoming numbers
I'm calculating this. 4.bet-(2.bet-3.bet)= If greater than 20, bet on the number 10 ie x1.10
90.48-(23.93-69.36) = 135.91 >=20
He will bet x1.10 as it is greater than 20. If it wasn't big it will continue without betting. If he loses, he will double the amount of his original bet next time. The stake should be balance/10000, when the stake is 0 until you get a number greater than 20.
