Diarmuid O'Regan
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%".
Rode around 60 times a season, almost all over hurdles and fences, winning on 9% of them — level with the margin-free market read across the lifetime window (Fair A/E 0.97). Rode mostly for Chris Grant — 63% of rides in the window.
The record is strongest at Musselburgh (14.3%, n=35), clear of the rider's 8.6% baseline. Rides in big fields of 14 or more have been a poor signal at 2.6% (n=38, Fair A/E 0.50). The market has consistently overbet first rides on a horse: 5.4% strike, Fair A/E 0.68 and −67.00 to a £1 stake over 149 rides — those runners underperformed what the price implied. Chris Grant supplied 63% of the rides and matches the rider's average almost exactly (8.6%, A/E 1.01) — the market has that partnership priced right. The rider also read well on Good to Soft going (14.3%, n=98). The record read poorly on Heavy going — 2.3% over 44 rides, 6.3pts below the baseline. The market has consistently overbet the rider over 2m1f – 2m4f: Fair A/E 0.53 across 145 rides (4.1% strike, −106.78 to a £1 stake) — runners there underperformed what the price implied.
Riding patterns
the angles behind the record · vs 8.6% baselineEach tile is the record in that situation vs the 8.6% 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.

- Which course does Diarmuid O'Regan do best at?
- Musselburgh by strike rate: 5 wins from 35 rides (14.3%) 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.

- Chris Grant, with 255 rides since 2008 — 63% of the total. That pairing has won 22 (8.6%).
- What is Diarmuid O'Regan's Fair A/E?
- 0.97, from 403 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.
