It is with sadness that I have to tell you that I've found a guessing game which
can beat mine. It's by an economics professor, and it's based on stochastic
analysis (which is what many share trading systems are based on).

Over 201 tries, it beat my game by 8 points - though I think my game was
catching up towards the end.

note: where the professor's game predicted odds of 0.5 for either button, I
always selected the left.
