Willie Musson
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%".
Sent out around 160 runners a season, almost all on the flat, winning with 9% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.91).
The record is strongest at Yarmouth (14.3%, n=70), clear of the yard's 8.5% baseline. It is weakest at Newmarket (0% over 31 runners) — the widest gap in the record. New recruits from other stables on their first run struggle at 0% (n=30, Fair A/E 0.00). The market has consistently overbet horses returning fresh after 61+ days: 6.2% strike, Fair A/E 0.84 and −52.62 to a £1 stake over 241 runners — those runners underperformed what the price implied. Stevie Donohoe rode 21% of the entries and matches the yard's average almost exactly (8.9%, A/E 0.88). The yard also read well off a 0-7-day break (27.5%, n=51). The stable star of the record was Bold Adventure (GB) — 12 wins from 88 runs for the yard. Seasonally, the yard fired Nov–Jan.
Yard patterns
the angles behind the record · vs 8.5% baselineEach tile is the record in that situation vs the 8.5% 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.
