Shelley Birkett
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 120 times a season, almost all on the flat, winning on 8% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.95). Riding last-time-out winners the record reads 13% (112 rides). Rode mostly for Julia Feilden — 54% of rides in the window.
The record is strongest at Lingfield (11.9%, n=143), clear of the rider's 7.8% baseline. It is weakest at Chelmsford City (AW) (2.4% over 85 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 13.4% (n=112, Fair A/E 0.87). Julia Feilden supplied 54% of the rides and matches the rider's average almost exactly (8.3%, A/E 0.97) — the market has that partnership priced right. One Group or Graded win sits in the archive record — the biggest prize the rider has landed: the Coral Sprint Trophy at York (Oct 2016, £62,250). The standout partner of the record was Limerick Lord (IRE) — 5 wins from 43 rides together. Seasonally, the rider fired Dec–Jan.
Riding patterns
the angles behind the record · vs 7.8% baselineEach tile is the record in that situation vs the 7.8% 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.

- Which course does Shelley Birkett do best at?
- Lingfield by strike rate: 17 wins from 143 rides (11.9%) 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.

- Julia Feilden, with 703 rides since 2008 — 54% of the total. That pairing has won 58 (8.3%).
- What is Shelley Birkett's Fair A/E?
- 0.95, from 1,283 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.
