I don't really know. In order to even have a hope at determining the exact probability of a session winning at least $2,500, I would obviously have to know everything that the system does and under what conditions the system does it, assuming what the system does given a certain specific condition is always the same.

Even then, it would be tough to come up with an exact probability.

The only thing I would like to think is that his system makes hitting the win goal more likely as opposed to less likely in a given session, but I don't really know that for sure. I assume that's what the goal of it is.
