Reading Andrew Beyer is at once informative and entertaining, which anything on handicapping has no excuse not being. While his first book introduced speed figures, and his second mixed the application of them with an appreciation of other aspects of handicapping, this book revisits the holistic approach - always emphasizing speed figures - in an era when everyone has access to more information than ever, and many even know how to use it. What makes reading Beyer so fascinating is that one is made to see, vividly, the endless testing and working out of new ideas and approaches, in the stories - one might call them lessons - he recounts (the chapter on turf betting is a classic of sports writing). Beyer, like Bill James, is a scientist, and thinks like one, to the edification of all who choose not to keep recycling the same old bromides, and making the same old mistakes. People like Beyer and Steve Davidowitz are largely responsible for the ever-escalating arms race which parimutuel bettors are fighting amongst themselves. It's a wonderful game, but if you don't want to get left behind, better read this.
