This is a tweak of my "Tomahawk" system, --> Less numbers bet, less drawdowns. So, it *should* preform better. I expect a 70% winrate, anything higher than that would suprise me.
Procedure: Wait for a hit in column 1 or 3 within dozen 1 or 3. Now, bet 2 quads at the unhit part of that particular dozen hit. Also bet 2u on the opposite H/L.
Progression: double for each loss, until hit.
Bankroll: 100u playing with 1u bets
500u playing with 5u bets
2500u playing with 25u bets
I've made a video
First tests was played with 5u bets
