Gentlemen, my 1cent,
In double dozens bet,
Bet last dozen and next dz to the right,
Last =dz1, then bet dz1&2,
Last =dz2, bet dz2&3,
Last =dz 3, brt dz3&1, zero disregard, and unfortunate losses...
When you make a long history bet as a long 300spins, you will see long sequence of streaks,
The double hit will be as long as 20 to 30 hit continuos hit, or 30spin with only few losses in between,
We can't predict, but we can see after long streaks of dd hit, then , the other side will hit too, thus after 300 ispins, the flatbet result, mostly always within math HE EXPECTATION. ...Try it, you may like it...
