You guys are so confused it is quite hilarious. Ever heard of a bell curve? No one claims that any player will precisely see the expected return of a game. Actual returns will vary considerably at low sampling rates (hands) but eventually converge on the expected return. And, there is no betting system that can change the return of a random/fair game. That's not theory, it has been proven. All you are doing with your win goals and loss limits is working a betting system.

Don't confuse markets with random VP games. Markets are not random.
