Why a Jockey Rating Should Measure Profit, Not Ability

Recorded August 2025 for The Grind Ep3: Mastering Betfair SP, Lays & Market Angles – A Professional Approach. Any figures mentioned are from that time.

When people see a jockey rating on The King Zone, the first thing they assume is that it ranks riders from best to worst. It does not. The jockey edge runs from minus ten at the bottom to plus fifteen at the top, and what it measures is profitability, not ability. It is not about how many winners a rider kicks home. It is about how you have gone backing them under certain circumstances, at different tracks, in different riding conditions, and all of that sits inside the algorithm.

Where to find it and how it reads

The jockey edge sits under the runner details on the race page. Take a Toowoomba race as an example. Bayless rates minus seven. Shear Gold rates minus ten, and minus ten is as bad as it gets. Elsewhere in the same race you will find a rider on plus two, and others sitting around square. The scale is wide on purpose, because the gap between the riders who have been worth following and the riders who have cost you money is wide.

This is where the confusion usually starts. You might see James McDonald on minus two or minus three. Obviously he is a champion jockey and the best in the country. The rating is not arguing with that. It is telling you what has happened to your money backing that rider in that set of conditions. Ability and profitability are two different questions, and I only care about the second one.

What happens when you layer it over the lays

To show how much the figure matters, I took the official lays over a period, all odds, and then filtered on jockey edge alone. First I looked only at the underperforming riders, the minus ten to minus five band. That gave 417 lays. Forty times you would have laid the winner, so the winner came up about nine and a half percent of the time, and you would have won sixteen percent before commission.

Then I flipped the filter to the profitable end of the scale and ran the same set of official lays. The result turned over completely. Those are horses I did not like, but with a profitable rider aboard, backing them returned about eight percent on turnover. Same selections, same period. The only thing that changed was who was in the saddle. Going back and running the underperforming band again brought the minus sixteen straight back up. That is the difference the one filter made.

Building systems inside the system

This is the point I keep coming back to. It is not just about taking the official tips and leaving it there. The tips merging with the extra information you can pull yourself is where you create systems within the system, and that is how you build layers into your approach rather than relying on one output.

So use the jockey edge as a filter, not as a leaderboard. Check it on your own selections, see which end of the scale your bets keep landing on, and let that shape what you keep and what you leave alone.
