Robert Tart
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 70 times a season, almost all on the flat, winning on 12% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.07). Riding last-time-out winners the record reads 19% (132 rides).
The record is strongest at Haydock (19.4%, n=36) and Chelmsford (AW) (18.2%, n=66) — all clear of the rider's 11.5% baseline. Rides on last-time-out winners have been a positive signal at 18.9% (n=132, Fair A/E 1.15), but rides in big fields of 14 or more have been a poor signal at 7.9% (n=164, Fair A/E 1.16). Jane Chapple-Hyam supplies 9% of the rides and edges the rider's average (15% vs 11.5%, A/E 1.36) — the partnership beats the margin-free market read. The rider also reads well over 1m5f – 2m (19.7%, n=76). 4 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Grosvenor Sport Handicap at Goodwood (Aug 2017, £62,250). Seasonally, the rider fires Jan–Apr.
Riding patterns
the angles behind the record · vs 11.5% baselineEach tile is the record in that situation vs the 11.5% baseline — descriptive splits with the sample always shown, for you to weigh. 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 Robert Tart's strike rate?
- Robert Tart has won 153 of 1,336 rides since 2008, a strike rate of 11.5% (as at 14 November 2026). Figures are computed from our own results archive.
- Which course does Robert Tart do best at?
- Haydock by strike rate: 7 wins from 36 rides (19.4%) since 2008. 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.
- Which yard does Robert Tart ride most for?
- Jane Chapple-Hyam, with 120 rides since 2008 — 9% of the total. That pairing has won 18 (15%).
- What is Robert Tart's Fair A/E?
- 1.07, from 1,329 rides with a computed fair probability since 2008. 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.
