This is betting 30 numbers.
Trigger: Look at the history of spins and locate the 3 last hit splits in either high or low (doesn't matter witch) now all 6 unhit splits are bet except the 3 last hit splits in that particular high or low. Next place 6u on the opposite high or low.
Progression: Re-track after one hit. double for each loss, and reset after 2 hits in a row. 2 hits is always enough to recover and be ahead of the game. This is very good since it handles losses without problem. doesn't matter 4-5 losses etc with 2 hits you always recover. Furthermore it would be extreme bad luck if 3 splits repeats 4-5 times.+3 (initial bet) so that is a rare event
You keep to amaze me....really
