As usual it looks good
Have you tried a slower progression with the unhit dozens? If you went 3,6,9,12 and so on it would increase win rate but slower bank progression
Thanks

The progression is perfected as much as it can be; it's a doubledozen bet, really (2 quads within one doz) The +1u progression works fine, but it busts sometimes, (not too often) therefore to play with a wingoal and stoploss is essential, it can go very far and survive many losses before hit. I think it's perfected. We'll see how far it can go.
Cheers
