I thought I should also point out what I'm up to. While at the cottage I'm trying to figure out how to use opposing information. For example, we would like to bet on favourites but they don't come in as often as the word favourite might imply. So if we 'know' that horse won't be first, what can we do with the other information? Same thing with the absolute longshot.

I'm using a genetic algorithm to search for the appropriate rules. I'm also trying it in Prolog. Admittedly this is to keep up my experience on both but it's a very interesting application for them!

Thanks for all the info, directly or indirectly supplied. Results should be here first week in September.
