A. Slattery
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 470 runners a season, winning with 10% of them — beating the margin-free market read across five seasons (Fair A/E 1.12). Horses with headgear back on after a bare run strike at 14% (79 runs). The yard is in form now — 7 winners in the last fortnight, above its own baseline.
The record is strongest at Killarney (19.5%, n=77), clear of the yard's 10.1% baseline. A horse having headgear put back on after a bare run has been a positive signal at 13.9% (n=79, Fair A/E 1.66), but a horse in first-time headgear has been a poor signal at 4% (n=100, Fair A/E 0.62). The market has consistently overbet in Group and Graded company the record: 4.8% strike, Fair A/E 0.55 and −72.70 to a £1 stake over 145 runners — those runners underperform what the price implies. Right now the yard is firing: 7 winners from 35 runners in the last 14 days (20%, 9.9pts above the 10.1% baseline). Andrew Slattery rides 40% of the entries and matches the yard's average almost exactly (10.1%, A/E 1.15) — the partnership beats the margin-free market read. The yard also reads well in NH Flat races (21.5%, n=79) and in Chase races (19.4%, n=62). 12 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the COLM QUINN BMW Mile Handicap at Galway (Jul 2016, £70,800). The stable star of the record: Sharjah (IRE) — 15 wins from 151 runs for the yard. Seasonally, the yard fires Jul–Aug.
Yard patterns
the angles behind the record · vs 10.1% baselineEach tile is the record in that situation vs the 10.1% 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.
