Read it last month. Good read. Sounds like a decent approach to baseball wagering, but to do what Peta did in the book, you'd have to: have a 6 figure bankroll to play with, and you'd have to have a shitload of spare time to update stats and get down on too many games to grind out a profit. After his 40% profit in 2011, Peta only cleared a 14% profit in 2012. I haven't heard how he is doing in 2013.
Peta tells the reader what he did and how he did it step by step, which initially made me want to start a spreadsheet and mock his work, but I have a feeling that we do not know every part of his system. Sharing it with the public would enable the books to adjust their lines and render it obsolete. Or maybe not. Either way, if I had a 6 figure bankroll and 8 hours a day to chart stats and place bets, it sounds like a decent way to grind out a profit, but I don't have either, so...
