Columns use to repeat more than twice frequently:
-This is a similar system as "Dozen Repeater" but it's played with columns and 4 splits bet.
Trigger: wait for a column to repeat, now bet for it to repeat again ONCE: -Bet the two unhit dozen in that repeating column with 4 splits. (calculating from last hit in that particular column)
For an example Trigger hit (a repeating column); 1,13. Now split 1/4, 7/10 and 25/28, 31/34 are bet.
STOP after 1 spin. if no hit, wait for the next trigger (a repeating column)
Progression 4 splits negative 1. 1. 1. 1. 2. 2. 3. 4. 5. 6. 8. 10. 13. 17. 22 28 36 46 59
first test was played with 5u bets.
Test 2. Played with 1u bets
