Valentin Seguy
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 20 times a season, almost all on the flat, winning on 9% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.96). Riding last-time-out winners the record reads 15% (40 rides).
It is weakest at Saint-Cloud (FR) (2.5% over 40 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 15% (n=40, Fair A/E 1.26), but rides in big fields of 14 or more have been a poor signal at 4.7% (n=235, Fair A/E 0.81). The market has consistently overbet horses returning fresh after 61+ days: 6.7% strike, Fair A/E 0.74 and −17.30 to a £1 stake over 163 rides — those runners underperform what the price implies. F Rohaut supplies 12% of the rides and matches the rider's average almost exactly (9.4%, A/E 0.62). The rider also reads well off a 15-30-day break (12.5%, n=88). 6 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Criterium de Maisons-Laffitte at Chantilly (FR) (Oct 2020, £70,622). Seasonally, the rider fires Oct–Nov.
Riding patterns
the angles behind the record · vs 8.7% baselineEach tile is the record in that situation vs the 8.7% 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.

- What is Valentin Seguy's Fair A/E?
