Man, in fact, I absolutely agree with you ... Just recently, I decided to test the doubling strategy, (if you can call it that) but it didn't end as I expected. I assumed that using a 47% chance, and doubling the rate in case of a loss will sooner or later pay for itself, but I could not imagine that with such a high probability I will have 10 losses in a row. So from my experience I can say that not everything depends on statistics.
