Zac Purton
Fair A/E compares wins with a margin-stripped market expectation. Favourite-heavy samples — top yards, leading riders — naturally read a few points warm, so 1.05 means "beat the margin-free market read", not "the market underrates this by 5%".
Rides around 40 times a season, almost all on the flat, winning on 21% of them. First rides on a horse are a strength: 25% on the first captured pairing (132 rides).
First rides on a horse have been a positive signal at 25% (n=132, Fair A/E 1.22), but rides in big fields of 14 or more have been a poor signal at 15% (n=80, Fair A/E 0.79). The rider also reads well in Class 4 (24.4%, n=45). The record reads poorly off a 15-30-day break — 13.2% over 38 rides, 7.6pts below the baseline. 2 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the The National Day Cup at Sha Tin (HK) (Oct 2026, £338,722).
Riding patterns
the angles behind the record · vs 20.8% baselineEach tile is the record in that situation vs the 20.8% baseline — descriptive splits with the sample always shown, not tips. Tiles under 30 runs render muted. First rides are the first captured pairing of horse and rider; last-time-out winners are horses whose previous captured run was a win; claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races.

Quick answers
- What is Zac Purton's strike rate?
- Zac Purton has won 37 of 178 rides since 2022, a strike rate of 20.8% (as at 20 October 2026). Figures are computed from our own results archive.
- Which course does Zac Purton do best at?
- Sha Tin by strike rate: 25 wins from 119 rides (21%) since 2022. Read from the 15 courses with the most rides on the same basis, and only those with at least 30 — a small sample cannot top the list, and a rarely-visited course is not in the comparison.
- What is Zac Purton's Fair A/E?
- 1.05, from 75 rides with a computed fair probability since 2022. Fair A/E compares actual wins with a margin-stripped market expectation, so 1.00 is par: above it the wins came at bigger prices than the margin-free market implied, below it they did not.
