J-L Guillochon
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, across both codes, winning with 12% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.12).
In Group and Graded company the record reads poorly at 4.7% (n=43, Fair A/E 0.65). The market has consistently overbet horses returning fresh after 61+ days: 9.2% strike, Fair A/E 0.82 and −45.20 to a £1 stake over 142 runners — those runners underperform what the price implies. Antoine Hamelin rides 19% of the entries and edges the yard's average (15.9% vs 11.8%, A/E 2.08) — the partnership beats the margin-free market read. The yard also reads well off a 15-30-day break (16.9%, n=71) and over 1m2f – 1m4f (16.2%, n=99). The record reads poorly in Class 1 — 4.7% over 43 runners, 7.1pts below the baseline. The market has consistently overbet the yard off a break of 180+ days: Fair A/E 0.59 across 55 runners (7.3% strike, −32.90 to a £1 stake) — runners there underperform what the price implies. 3 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Prix Lutteur III at Auteuil (FR) (Mar 2014, £45,000). The stable star of the record: Sidi Bouknadel (FR) — 5 wins from 26 runs for the yard.
Yard patterns
the angles behind the record · vs 11.8% baselineEach tile is the record in that situation vs the 11.8% 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.
