I've been playing around with this for years. Not only do they have an edge when it's time to make a wager, but they also have an edge because they have figured out a way to produce fair odds without actual handicapping. Handicapping, on a daily basis, can take a lot out of you ... it's tiresome when it's done by hand, like I do it. I'm lucky if I can [thoroughly] handicap a handful of races per day. They, on the otherhand, can generate fair odds for all the races, at all tracks, everyday ... the computer never gets tired. The amazing thing to me is that the data their computer uses to compute fair odds is done from data you can find in the DRF ... as far as i'm aware. I've never heard of any of these computer teams feeding their computers Thoro-Graph numbers. My methodology utilizes what I consider the single most important factor ... speed figures ... Thoro-Graph speed figures.
