Olivia Haines
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 15% of them — beating the margin-free market read across five seasons (Fair A/E 1.61). Rides mostly for Stuart Williams — 48% of rides in the window.
First rides on a horse have been a poor signal at 9.2% (n=65, Fair A/E 1.23). Claiming rides are the standout value angle: 15.1% strikes only just above baseline, but Fair A/E 1.63 and +40.38 to a £1 stake over 106 rides — a record the market has persistently underpriced. Stuart Williams supplies 48% of the rides and beats the rider's average (23.6% vs 14.9%, A/E 2.06) — the partnership beats the margin-free market read. The rider also reads well in Class 5 (21.7%, n=46) and off a 15-30-day break (20%, n=55). The record reads poorly in Class 6 — 8.8% over 34 rides, 6.1pts below the baseline.
Riding patterns
the angles behind the record · vs 14.9% baselineEach tile is the record in that situation vs the 14.9% 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.
