Hi Kav . . .
Here's another idea, rather it's an extension of my previous one.
Track the repeaters until you have 1 repeater in 2 different dozens and 0 repeaters in the 3rd dozen.
DZ 1 DZ2 DZ3
# Repeaters: 1 1 0
Then bet ALL the STRAIGHT numbers in both dozens with the 1 repeater. We are gambling that one of the numbers in the 2 dozens with 1 repeaters will repeat again before any one number the dozen with 0 hits twice.
Using the same selection of waiting for 21 spins to bet, I did a quick 100,000 spin test and showed a profit of 1,933 units with largest drawdown of 3,745 units. This is a much better return.
Therefore, with this higher profit, I then dropped the spin count from 21 to 3 to get more bets and got the following results: Tested for 250,000 spins with a profit of 125,433 units. This was done with a 20,000 stop loss as we had a maximum drawdown of 140,530 which would not occur with the stop loss.
I have again attached the Excel Sheet Tracker that generated these results.
