If I'm repeating myself, ignore this, I'm talking to myself. After so much playing/testing, playing/testing etc....... I feel 100%, you have to have rotating bets.
Meaning, NOT sticking with the same numbers until "such-n-such" happens.
In my opinion, 1-3 consecutive spins of the same numbers (2-4 numbers max), if no hit, move on. You can keep the SAME reasons (style) for the next bets but different numbers and all flat betting.
This thread is not about WHAT or WHY to bet, its more about, how long to bet it.
Also, I am not stating, don't bet those numbers again in the session, just saying, don't sit around and WAIT for your numbers to hit. Only my viewpoint fellas.
