Custom Report








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 :

  • Win Percentage. For example, Horses with a SP of 3-1 on average may win 23% of the time.
  • Place Percentage. For example, Horses with a SP of 6-4 on average may be placed 62% of the time.
  • Percentage of Other Horses Beaten. For example, in an 11 runner race, the winner has beaten 100% of the other horses, the horse on last place has beaten 0% of the other horses, while the horse in 6th place has beaten 50% of the other horses (5 in front and 5 behind). It may be that horses with a SP of 2-1 beat 78% of the other horses on average while horses at 10-1 beat 37%.

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.

The Custom Report link allows the performances of an individual jockey, or jockey/trainer combination, to be analysed.
