KV,

I was wondering if you had progressed with your 'intellectual exercise' idea from a while ago.

I got my brother involved in a similar project recently using the neurals plus Unitab rating and Weight carried below the toppy. He wrote some code that could try 10,000 variations in less than a minute and optimise the factors automatically. He ended up with a set of factors that produced a 4% loss on turnover betting in every race over 16months. The factors were optimised for POT though and the results weren't reproducible in the 4 months of test data that I had. The strike rate was exactly the same though. We'll try again, optimising for SR instead of POT and see how it goes. I don't think it will match the -4%.

Cheers
