OK, i have done more testings with this one, and from the first session i got
9/10 wins. So,it's a strong trigger...
Pick one dozen (1 or 3), Now for each hit within that dozen, bet the "other" unhit SPLIT within the same column, within the same dozen, Also put 1u on the opposite H/L. When 3 splits bet, Start progression- Double up once, then double after each (2) losses.
BR: 200-300u (played with 1u bets)
Fist session (5u bets)
