Jessica Macey
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%".
Sends out around 180 runners a season, almost all on the flat, winning with 7% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.78).
A horse having headgear put back on after a bare run has been a poor signal at 2.6% (n=39, Fair A/E 0.32). The market has consistently overbet runners with a claiming rider up: 7.5% strike, Fair A/E 0.81 and −76.50 to a £1 stake over 214 runners — those runners underperform what the price implies. Lewis Edmunds rides 43% of the entries and matches the yard's average almost exactly (7.9%, A/E 0.81). The yard also reads well at trips under 6f (10.6%, n=216). The record reads poorly over 1m – 1m1f — 3.4% over 146 runners, 4pts below the baseline. The stable star of the record: Dark Side Prince (GB) — 11 wins from 49 runs for the yard. Seasonally, the yard fires Jul–Aug.
Yard patterns
the angles behind the record · vs 7.4% baselineEach tile is the record in that situation vs the 7.4% baseline — descriptive splits with the sample always shown, not tips. Tiles under 30 runs render muted. Headgear figures use the true-first definition (first gear appearance in the captured career); returns are gear back on after a bare run. Claiming riders are runs where the booked rider carried a weight claim. Group / Graded covers pattern and listed races.

Quick answers
- What is Jessica Macey's strike rate?
- Jessica Macey has won 65 of 880 runners since 2022, a strike rate of 7.4% (as at 27 October 2026). Figures are computed from our own results archive.
- Which course does Jessica Macey do best at?
- Yarmouth by strike rate: 5 wins from 44 runners (11.4%) since 2022. Read from the 15 courses with the most runners 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.
- Who rides most for Jessica Macey?
- Lewis Edmunds, with 379 runners since 2022 — 43% of the total. That pairing has won 30 (7.9%).
- Is Jessica Macey in form?
- Too few runners in the last 14 days to read — 7 runners, which is not a sample we will draw a conclusion from.
- What is Jessica Macey's Fair A/E?
- 0.78, from 874 runners with a computed fair probability since 2022. 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.
