This system i dont know, maybe appeared in the topic beforehand, but I think, the system is quiet underrated. Has potencial!

Game:We are watching at the wheel, and always bet on the incoming number, starting with 1 unit for 30x. Meanwhile my betting number has repeated, I won. When not, we double the unit, and go 30x with 2 units. If the number has repeated, we won, and start with 1 unit. If not won, double to 4 units, and go for 30x. We know, that numbers quiet often repeated, so this system i think, has a potencial. What would be the weakness of the system?

My first test: (image) 500 UNIT to 802 UNIT, so +302 profit after 305 spins. Wow!
