Seamus Mullins
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 230 runners a season, almost all over hurdles and fences, winning with 9% of them — level with the margin-free market read across the lifetime window (Fair A/E 0.98).
The record is strongest at Southwell (16.8%, n=101), clear of the yard's 8.6% baseline. It is weakest at Cheltenham (0% over 52 runners) — the widest gap in the record. In Group and Graded company the record reads poorly at 1.9% (n=106, Fair A/E 0.47). Debutants are the standout value angle: 7.8% strikes only just below baseline, but Fair A/E 1.41 and +126.50 to a £1 stake over 270 runners — a record the market has persistently underpriced. The market has consistently overbet a horse in first-time headgear: 5.4% strike, Fair A/E 0.72 and −51.00 to a £1 stake over 130 runners — those runners underperform what the price implies. Daniel Sansom rides 14% of the entries and matches the yard's average almost exactly (8.5%, A/E 0.94). The yard also reads well off a 0-7-day break (19.4%, n=93). The record reads poorly in Class 1 — 1.7% over 121 runners, 6.9pts below the baseline. 3 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the United House Gold Cup Handicap Chase at Ascot (Oct 2006, £61,970). The stable star of the record: Tommie Beau (IRE) — 15 wins from 54 runs for the yard. Seasonally, the yard fires Apr–Jun.
Yard patterns
the angles behind the record · vs 8.6% baselineEach tile is the record in that situation vs the 8.6% 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.

- What is Seamus Mullins's Fair A/E?
