Sean Corby
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 80 times a season, winning on 10% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.17). Riding last-time-out winners the record reads 14% (59 rides).
It is weakest at Curragh (2.1% over 47 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 13.6% (n=59, Fair A/E 1.09), but horses returning fresh after 61+ days have been a poor signal at 4.4% (n=90, Fair A/E 0.83). M Halford supplied 11% of the rides and sits below the rider's average (7.2% vs 9.8%, A/E 0.70). The rider also read well in Class 4 (16%, n=50). The record read poorly off a 61-180-day break — 3.2% over 62 rides, 6.6pts below the baseline. The market has consistently overbet the rider on Good to Firm going: Fair A/E 0.41 across 86 rides (3.5% strike, −66.25 to a £1 stake) — runners there underperformed what the price implied. Seasonally, the rider fired Jul–Sep.
Riding patterns
the angles behind the record · vs 9.8% baselineEach tile is the record in that situation vs the 9.8% 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 Sean Corby's strike rate?
- Sean Corby has won 61 of 620 rides since 2008, a strike rate of 9.8% (as at 6 November 2026). Figures are computed from our own results archive.
- Which course does Sean Corby do best at?
- Gowran Park by strike rate: 4 wins from 30 rides (13.3%) 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.
- Which yard does Sean Corby ride most for?
- M Halford, with 69 rides since 2008 — 11% of the total. That pairing has won 5 (7.2%).
- What is Sean Corby's Fair A/E?
- 1.17, from 618 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.
