I\'m sure the subset of trainer intent within an arsenal of data that would make the trainer live is a very useful tool. I\'m speaking more to the novice reader here that may only play a few races a year where horses are pointed to a race and as such, class moves will take on far less importance than in the throws of everyday racing. In these few big races, you\'re single most important factor in handicapping is who\'s the fastest, and when there is a clear cut standout, and yes the odds will probably be short, you\'ve a far superior chance of being right than with any other handicapping tool. As to the old key race angle, I look for big fields to most likely produce key races, which is why I went with the Bluegrass as a potential key to this years race(surface and time between aside), as it was the only race with a full field. And what did it get me, another knock on the head for wondering where the odds on CC(37-1) would be come post time and leaving him off because I though he\'d be less than 20-1, even though numbers and pattern still had him playable at less than 20-1. so far all the work and tape watching and analyzing of this yeas race, the seminar had a live long shot come in to fill out a nice exacta and other exotics who had it. Sure there were other ways to come up with CC, but this was the shortest clearest path.
