Ron,

As an example, I've just dug out some stats that I worked out from that site from way back in early 2000. It was based on the previous 18 months of racing. At the time, the three best jockeys to follow were Damien Oliver and the Cassidy brothers (Beadman wasn't riding then), so I did some research on them. In the case of the Cassidys, they are not nearly as successful these days, so these stats probably aren't worth a lot now, but these few examples just show how good that jockey stats database was. And remember these systems contain absolutely no rules at all about the form or odds of the horses they were riding.
