Query: Some comedy value

I bought this book based on its claim to provide mathematically sound analysis of gambling games, based on stock market strategies.Reading it led me to the conclusion that the author does not have even rudimentary knowledge of probability, expectation or house percentage. His "analysis" consists of doing sets of 100 rolls of dice on his kitchen table!He then goes on to the inescapable conclusion (to him) that the casinos are "cheating", since his schemes don't work there.I was so disgusted that I took the time to complain to the publisher, and ended up corresponding to the author himself, who repeated those claims. I even took the time to do a trivial analysis of his "half-peak" system, together with some extensive computer runs, just to show him how bad the systems are.
