calling denzie. single dozen question

[RouletteGhost]

Denzie. You say star on following the last dozen is solid

Can you explain how you play it

Id want to use it for chasing the previous column

How is it any different then 1 1 2 3 4 6 9 13 20

[denzie]

1-1
2-2
4-4
8-8
16-16
2-2
4-4
8-8
16-16
32-32

And here I stop if you hit that bad luck.
Choose a daily bankroll
and if u win 6of 7days then u got it.
