Is 10 000 spins enough?

[Takur]

Im currently looking at a system (method of play) where the max sequence of reds/blacks out in a row is 8 (from 10 000 spins obtained from hamburg casino)

Is this sufficient amount of spins to ensure that 12 reds or more do not come out in a row, because I am looking at betting on black to show with martingale after 5 reds out in a row.

Normally with normal red/black outcomes in 10 000 spins there would already be streaks of 15-20 to show and not limited to 8

Besides Martingale, is there any other method of play for such streaks?

Thanks
