As does Blaise Pascal, you are showing all possible outcomes of the dozens. A computer can analyze spin results against those "blocks" to find specific "live" pathways, narrowing down the possibilities to a progressively smaller number.
What I need to understand is if there will ever be a conclusive advantage that can be gained by this information. That I will discover when I program the analysis logic.
In general, like in a chess tree, the system will follow the spin input and reveal which of your "block" pathways are active. As more spins are added, a progressively smaller amount of pathways will be left.
It will be probably like you have said, we will need to take 70-30 shots or better, like looking for the majority being one particular result versus the smallest minority possible. The computer will be able to discover what the possibilities are and display them on a spin by spin basis.
