A similar system, perhaps more effective.
Place 3 streets within each dozen;
1/3, 4/6, 7/9, 13/15, 16/18, 19,21, 25/27, 28/30, 31/33.
Flatbet until 3 hits in a row.
When three hits in a row 1/3 street is moved to 10/12, 13/15 Street is moved to 22/24 and 25/27 is moved to 34/36.
+1 progression for each loss until 3 hits i a row (No progression when hit) After 3 hits in a row: Reset to minimum bet and move the streets in reverse order: 10/12 is moved back to 1/3, street 22/24 back to 13/15 and 34/36 back to 34/36.
Then continue flatbet until one loss, then start +1 progression for each loss until 3 hits in a row... then reset and move the streets.
Moving the streets in this way can delay loss
