It is well known that some jockeys ride a lot more winners than others. That might be because they are better jockeys, but it might be because they are riding better horses or just riding a lot more often than the other jockeys. Some jockeys have many followers, so horses they ride, tend to have SPs which are shorter than they otherwise would be. Some jockeys have few followers so their mounts tend to have SPs which are longer than they otherwise would be. What is important for the backer (or layer) is to know whether a particular jockey performs better or worse than expected according to the SPs of the horses that they ride. For example, does Jockey A tend to perform better or worse than Jockey B on 10-1 shots. These ratings are an attempt to indicate which jockeys are better or worse than average, taking into account the SPs of the horses that they ride. The ratings are calculated as follows :
Firstly, by analysing a lot of races, I have calculated the average finishing
position of horses at all different values of SP. The finishing
positions are expressed in 3 different ways :
Secondly, the finishing position of each of a particular jockey's mounts are compared to the average for horses at that SP. Taking an average of these comparisons gives a rating for the jockey. A rating greater than 100 indicates that the jockey tends to finish in a better position than average, while a rating less than 100 indicates that the jockey tends to finish in a worse position. Jockeys with higher ratings should give better value to the backer. Click on the link on the left for ratings. The Jockey Form links on the left lead to pages giving the recent form of jockeys. The Custom Report link allows the performances of an individual jockey, or jockey/trainer combination, to be analysed.
