Now I know this is a different context to horseracing. But I can vouch for the benefits of using the principles illustrated above; the contrarion approach to starting by throwing masses of data and computing at a problem. In the race distance case above I was trying to find a way of 'getting into the head of the trainer/connection' about entering a horse to have a chance of winning at a good price.
Sorry I missed this when you 1st posted - very nice example of what most traditional form readers overlook - ie - the possibility that previous form may not be all that's required to win the race -as you say the market is driven by such form.
How often do we second guess trainers ! - far to often
