I played around with the UniTAB ratings quite some time ago. Used a quick and dirty method to convert them to prices, and used the resulting price as the maximum I'd accept. So if rated price was 2.5, I'd back the horse if it was under that price, but not if it was over. Backing only the favourite it was actually quite profitable on the single day I tried it out. Ages ago now but I think I was up 10 or so units on the Saturday.

Makes you wonder where the value really lays.
