D Sourdeau De Beauregard
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 50 runners a season, almost all over hurdles and fences, winning with 12% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.14). New recruits from other yards win at 16% first time out (56 runs).
The record is strongest at Compiegne (20.9%, n=182), clear of the yard's 12.4% baseline. New recruits from other stables on their first run win at 16.1% (n=56, Fair A/E 1.56), but in Group and Graded company the record reads poorly at 8.9% (n=214, Fair A/E 0.97). Debutants are the standout value angle: 12.2% strikes only just below baseline, but Fair A/E 1.30 and +71.30 to a £1 stake over 245 runners — a record the market has persistently underpriced. Clement Lefebvre rides 14% of the entries and edges the yard's average (15.3% vs 12.4%, A/E 1.16) — the partnership beats the margin-free market read. The record reads poorly in Class 1 — 8.7% over 219 runners, 3.7pts below the baseline. 19 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Prix des Drags at Auteuil (FR) (Jun 2022, £83,193). Seasonally, the yard fires Apr–Jun.
Yard patterns
the angles behind the record · vs 12.4% baselineEach tile is the record in that situation vs the 12.4% 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.
