Carla O'Halloran
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 10 runners a season, almost all on the flat, winning with 9% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.16).
The record is strongest at Deauville (FR) (14.3%, n=49), clear of the yard's 8.9% baseline. Horses returning fresh after 61+ days have been a poor signal at 4.8% (n=84, Fair A/E 0.70). Fabien Lefebvre rides 68% of the entries and matches the yard's average almost exactly (8.2%, A/E 1.14) — the partnership beats the margin-free market read. The yard also reads well over 1m2f – 1m4f (20%, n=35) and off a 31-60-day break (18.9%, n=37). The market has also underrated the yard on Standard (AW) going: Fair A/E 1.83 across 90 runners (12.2% strike, +20.10 to a £1 stake). The record reads poorly off a break of 180+ days — 2.6% over 39 runners, 6.3pts below the baseline.
Yard patterns
the angles behind the record · vs 8.9% baselineEach tile is the record in that situation vs the 8.9% baseline — descriptive splits with the sample always shown, for you to weigh. 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. The same beliefs, tested across every yard and every GB and Irish race since 2005: Racing myths.
