You can get quite rich if you can monetize patterns that are as small as 7 and even just 12 numbers. I congratulate you for trying to see that way. The reason does not really matter much. What always matters is what I have called the effectiveness states, or the conditions. Those condition are as if you are in a condition of where you are seeing it working for you. Some have called that condition a kind of premonition state. I have called it when you are guessing and it is working for you very wellstate, the "effectiveness state." These conditions come and go. The math oriented statistical absolutist types have stated that there is no possibility for predictions to be possible. It's like stating the obvious and then expecting a prize for stating the obvious. Of course there is no capability for prediction to be possible when you consider that you don't care if you have magical powers or not. And you don't. All that matters is if you are seeing a coincidence where your trends are working in conjunction with your bets. In other words you are in a kind of sequence with everything working. You can believe that you have encountered a temporary state of seeing bias in a wheel. It does not matter why you believe what you believe. What matters is if you are in a win streak. Now does that help you or not?
