William Haggas
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 590 runners a season, almost all on the flat, winning with 22% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.08). The edge shows sharpest with horses returning fresh: 24% off breaks of two months or more (1,707 runs). The yard is quiet just now — 6 winners in the last fortnight, below its own baseline.
The record is strongest at Ripon (36.3%, n=179), Lingfield (34.3%, n=134) and Beverley (33.3%, n=96) — all clear of the yard's 21.5% baseline. It is weakest at Newmarket (12.1% over 782 runners) — the largest sample in the record, and the widest gap. Debutants struggle at 13.1% (n=1,638, Fair A/E 0.96). A horse having headgear put back on after a bare run are the standout value angle: 20% strikes only just below baseline, but Fair A/E 1.37 and +5.86 to a £1 stake over 120 runners — a record the market has persistently underpriced. Right now the yard is in a quiet spell: 6 from 52 runners in the last 14 days (11.5%, 10pts below the 21.5% baseline). Tom Marquand rides 19% of the entries and matches the yard's average almost exactly (21.4%, A/E 1.06) — the partnership beats the margin-free market read. 334 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Royal Bahrain Irish Champion Stakes at Leopardstown (Sep 2024, £712,500). The stable star of the record: Hamish (GB) — 15 wins from 29 runs for the yard. Seasonally, the yard fires Feb–Apr.
Yard patterns
the angles behind the record · vs 21.5% baselineEach tile is the record in that situation vs the 21.5% 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 1) · top-rated on KTB Rating in 11 runs (won 3) · fastest on KTB Speed in 7 runs (won 2) · to 31 Oct 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.
