C S Shum
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 30 runners a season, almost all on the flat, winning with 9% of them. The edge shows sharpest with horses returning fresh: 12% off breaks of two months or more (41 runs).
Horses returning fresh after 61+ days have been a positive signal at 12.2% (n=41, Fair A/E 0.00). The yard also reads well off a 61-180-day break (15.2%, n=33). One Group or Graded win sits in the archive record — the biggest prize the yard has landed: the King's Stand Stakes at Ascot (Jun 2012, £198,485).
Yard patterns
the angles behind the record · vs 9.2% baselineEach tile is the record in that situation vs the 9.2% 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.
