First let me thanks you for the effort you put and your willingness to share your system.
Before you get excited and "VERBALLY ATTACK" me and others on this board, let me run by you how I played your system/approach using a single zero Roulette.
Please correct me if the approach is wrong:
1. I tracked 6 numbers and wrote down its dozen as the number appeared.
2. I started to bet 1 unit as follow:
Number captured 6, 33, 3, 1, 22, 16 it is mapped to dozens:
1, 3, 1, 1, 2, 2
Starting with a flat bet, meaning placing 1 unit , I placed a bet on the first dozen. Regardless win or loss, meaning if I won I removed the bet from the first dozen and moved it to the next location which was the 3rd dozen. If I loss on the first number/dozen, I still remained with 1 unit and placed a flat bet on the 3rd dozen, etc... the total movements/bets were for the duration of the 6 dozens/numbers.
Step 2: since I was in a negative I increased the bet to 3 unit following the latest 6 dozens. I played that. Once the total winning vs. loss became positive I lower the bet to 1 unit.
The problem started when I started to face the streaks where my bet following the dozen handed up on different dozens. Even when I won, it was only 1 bet out of the 5 losing bets.
My progression was 1,3,5,8, 13.
Please let me know if I played that correct. If I didn't please correct me.
