Leanne Breen
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 20 runners a season, almost all on the flat, winning with 5% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.76). With a claiming rider up the record reads 7% (111 runs).
The yard also reads well off a 0-7-day break (9.7%, n=31) and on Good going (8%, n=75). The record reads poorly on Soft going — 0% over 51 runners, 4.5pts below the baseline. The market has consistently overbet the yard over 1m – 1m1f: Fair A/E 0.34 across 61 runners (1.6% strike, −49.00 to a £1 stake) — runners there underperform what the price implies.
Yard patterns
the angles behind the record · vs 4.5% baselineEach tile is the record in that situation vs the 4.5% 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.

- What is Leanne Breen's Fair A/E?
- 0.76, from 356 runners 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.
