Glad to hear it BA.
Which of the 3 options did you use ? .How many trials did you give it ? Theoretically it should win 2 in 9 bets.
Actually now I remembered when I tried it about a month ago that I've not used your boards,neither flat betting.
I was betting the 2 last spun dozens for a repeat,if won then parlay it for one more time only.
The trigger was to see 2 dozens without any repeat,if bet was lost,then on the next trigger had a higher amount to parlay.
It's like expecting 2 dozens to occur for three consecutive times,or a single dozen not to come for three times in a row.
I think this way is much different from yours,it's being some time since I've tested it,that's why I've confused it with yours.
