Racer,

I like the research and try and find things which work well.

Its obvious that the horse that runs the fastest time will win and therefore the horse should be rated by the potential times they could run in the race. For example a horse running 1.00 consistently should be a horse that is consistently running 1.10 .

The problem arises when horses do not run to their best times or even their avg times. This is where other form analysis needs to be taken into account to determine the fitness of the horse and whether any improvement can/should be expected.

I think the main reason people don't use it is because it is hard to find and compute yourself.

Good Luck.
