Jason Maguire
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 520 times a season, almost all over hurdles and fences, winning on 19% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.05). Riding last-time-out winners the record reads 27% (722 rides). Rode mostly for Donald McCain — 59% of rides in the window.
It is weakest at Cheltenham (5.8% over 139 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 27% (n=722, Fair A/E 1.05), but in Group and Graded company the record reads poorly at 6.6% (n=151, Fair A/E 0.64). Donald McCain supplied 59% of the rides and matches the rider's average almost exactly (20.7%, A/E 1.01) — the market has that partnership priced right. The record read poorly in Class 1 — 8.5% over 317 rides, 10.3pts below the baseline. 11 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the John Smith's Grand National Chase at Aintree (Apr 2011, £535,135). The standout partner of the record was Peddlers Cross (IRE) — 9 wins from 15 rides together. Seasonally, the rider fired Nov–Dec.
Riding patterns
the angles behind the record · vs 18.8% baselineEach tile is the record in that situation vs the 18.8% 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.

- Which course does Jason Maguire do best at?
- Sedgefield by strike rate: 46 wins from 167 rides (27.5%) 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.

- Donald McCain, with 2,468 rides since 2008 — 59% of the total. That pairing has won 512 (20.7%).
- What is Jason Maguire's Fair A/E?
- 1.05, from 4,163 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.
