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 240 runners a season, winning with 9% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.06). Horses with headgear back on after a bare run strike at 13% (204 runs). The yard is quiet just now — 1 winner in the last fortnight, below its own baseline.
The record is strongest at Wexford (22.5%, n=40) and Kilbeggan (16.7%, n=60) — all clear of the yard's 8.7% baseline. A horse having headgear put back on after a bare run has been a positive signal at 13.2% (n=204, Fair A/E 1.82), but a horse in first-time headgear has been a poor signal at 3.3% (n=184, Fair A/E 0.52). The market has consistently overbet in Group and Graded company the record: 5.2% strike, Fair A/E 0.62 and −121.62 to a £1 stake over 230 runners — those runners underperform what the price implies. Right now the yard is in a quiet spell: 1 from 21 runners in the last 14 days (4.8%, 3.9pts below the 8.7% baseline). Andrew Slattery rides 32% of the entries and matches the yard's average almost exactly (9.3%, A/E 1.08) — the partnership beats the margin-free market read. 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 8.7% baselineEach tile is the record in that situation vs the 8.7% 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.

KTB’s figures
the forward record · since 5 Oct 2026KTB’s figures on this yard’s runners since 5 Oct 2026: the KTB Selection in 8 runs (won 3, 1 did not run) · top-rated on KTB Rating in 5 runs (won 3) · fastest on KTB Speed in 9 runs (won 1, 2 did not run) · to 3 Nov 2026.
Each pick was a KTB figure’s choice before the off — the published KTB Selection, the top-rated horse on KTB Rating, the fastest on KTB Speed — settled against the result the next morning and never worked out again; “did not run” is counted apart. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.
