Walter Swinburn
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 360 runners a season, almost all on the flat, winning with 11% of them — level with the margin-free market read across the lifetime window (Fair A/E 1.00). Horses in first-time headgear strike at 15% (83 runs, true-first definition).
The record is strongest at Doncaster (18.8%, n=32), clear of the yard's 11.1% baseline. It is weakest at Lingfield (AW) (5% over 80 runners) — the widest gap in the record. A horse in first-time headgear has been a positive signal at 14.5% (n=83, Fair A/E 1.50), but debutants struggle at 3.2% (n=126, Fair A/E 0.57). Adam Kirby rode 48% of the entries and matches the yard's average almost exactly (11.9%, A/E 1.02) — the market has that partnership priced right. The yard also read well on Soft going (18.2%, n=66) and at trips under 6f (17%, n=94). 7 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the 47th John Smith's Cup Heritage Handicap at York (Jul 2006, £93,480). The stable star of the record was Stotsfold (GB) — 9 wins from 29 runs for the yard.
Yard patterns
the angles behind the record · vs 11.1% baselineEach tile is the record in that situation vs the 11.1% 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.
