I would like to come back to this topic asking if someone has coded he system as Belgian has so clearly explained,that is:

64 zero an a 1,both with 50:50 or 75:25 solutions.

I have used Johnson progression,but not in this clever way,for a few thousands spins,but it failed.

I'm afraid that also the "Belgian way" doesn't resist to 100.000 spins for instance.

I understand perfectly the principle 65/135,but I think that variance(the way W and L appear) can beat the principle that in 200 spins there are no more than 135 losses.

Thanks
