Track last twelve spins. Which is the hottest dozen? Bet that dozen over the next 12 spins. When it hits, stop, wait for the 12 spins to finish, and repeat.
When the dozens hit the same number of times i.e.
4 - 4 - 4
or
5 - 5 - 2,
don't bet, retrack the last 12 spins until there's one dominant dozen:
5 - 5 - 3 retrack
6 - 5 - 3 bet dozen 1.
Use fibo.
It's boring, I know.
May work well with lines, streets and ECs.
