Does anyone have experience with Sharp Football Analysis or with AG Sports or Joseph J Tuttle? They are services who claim great results. True or not??
I've read one of Tuttle's books (written under one of his many, many psuedonyms). It was absolute trash. Close to 100 percent useless. The typos riddling the book were bad enough, but one of the main parts of this particular book -- a key "formula" -- was filled with wrong information and, when I finally figured out the piece that was incorrect, the formula itself mathematically went just the opposite of what he claimed.
Worthless. His stuff is worthless.
