James O'Reilly
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 50 times a season, almost all on the flat, winning on 10% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.17).
It is weakest at Southwell (AW) (5.7% over 35 rides) — the largest sample in the record, and the widest gap. Jimmy O'Reilly supplied 36% of the rides and matches the rider's average almost exactly (10.4%, A/E 1.61) — the partnership beats the margin-free market read. The rider also read well on Good to Firm going (20.6%, n=34). The market has also underrated the rider over 6f – 7f: Fair A/E 1.48 across 97 rides (12.4% strike, +13.00 to a £1 stake). The record read poorly in Class 5 — 4.1% over 49 rides, 5.5pts below the baseline. The market has consistently overbet the rider off a 15-30-day break: Fair A/E 0.85 across 56 rides (7.1% strike, −37.50 to a £1 stake) — runners there underperformed what the price implied.
Riding patterns
the angles behind the record · vs 9.6% baselineEach tile is the record in that situation vs the 9.6% 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. Group / Graded covers pattern and listed races.
