Malcolm Jefferson
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 180 runners a season, almost all over hurdles and fences, winning with 14% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.04). Horses with headgear back on after a bare run strike at 21% (34 runs).
The record is strongest at Sedgefield (21.8%, n=193), clear of the yard's 14.3% baseline. It is weakest at Bangor-on-Dee (4.7% over 43 runners) — the widest gap in the record. A horse having headgear put back on after a bare run has been a positive signal at 20.6% (n=34, Fair A/E 1.47), but runners with a claiming rider up have been a poor signal at 10.1% (n=577, Fair A/E 1.01). Brian Hughes rode 36% of the entries and beats the yard's average (19.3% vs 14.3%, A/E 1.05) — the partnership beats the margin-free market read. The yard also read well on Heavy going (22.6%, n=164). The record read poorly over 1m2f – 1m4f — 4.3% over 46 runners, 10pts below the baseline. 13 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Betfair 'Fixed Brush' Handicap Hurdle at Haydock (Nov 2008, £62,620). The stable star of the record was Schinken Otto (IRE) — 12 wins from 89 runs for the yard. Seasonally, the yard fired Nov–Jan.
Yard patterns
the angles behind the record · vs 14.3% baselineEach tile is the record in that situation vs the 14.3% baseline — descriptive splits with the sample always shown, not tips. 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.
