This is another tweak of the "Anti-Street Repeater", 1-3 streets bet, in a progressive bet (half the carpet) that makes it easier to track. it's a 50/50% bet, played with a mild +1 progression.
TRIGGER- Divide the carpet into two parts HIGH/LOW. Pick one side. As one doublestreet hit, the unhit part of that doublestreet is bet with ONE STREET (1u), and 1u is bet on the opposite HIGH/LOW also. (Repeat procedure); continue playing like that until all 3 doublestreets are hit (3 streets bet) within the particular HIGH/LOW played OR if you get a hit STOP and restart with 1 street bet.
Progression: +1u bet for each loss, when 2-3 streets are bet, (only if the unbet street hit again) (same amount is bet on the opposite HIGH/LOW as the side you're playing with the streets) so, +1u on 2 streets, would bet +2u on the opposite HIGH/LOW and so on..
First two streets are bet with no progression, progression START when the third street is bet, OR +1u if any of the unhit streets hit when 2-3 streets are bet. WHEN HIT, if not recovered or reached a new high, SAME bet in the progression line is kept for the new trigger (one single street bet).
