William Muir & Chris Grassick
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 220 runners a season, almost all on the flat, winning with 11% of them — level with the margin-free market read across five seasons (Fair A/E 0.98). The edge shows sharpest with horses returning fresh: 13% off breaks of two months or more (128 runs). The yard is quiet just now — 1 winner in the last fortnight, below its own baseline.
The record is strongest at Nottingham (23.1%, n=39), clear of the yard's 10.6% baseline. Debutants struggle at 4.5% (n=88, Fair A/E 1.05). Horses returning fresh after 61+ days are the standout value angle: 12.5% strikes only just above baseline, but Fair A/E 1.47 and +39.75 to a £1 stake over 128 runners — a record the market has persistently underpriced. Right now the yard is in a quiet spell: 1 from 16 runners in the last 14 days (6.3%, 4.3pts below the 10.6% baseline). Lewis Edmunds rides 52% of the entries and matches the yard's average almost exactly (10.7%, A/E 1.01) — the market has that partnership priced right. The yard also reads well off a 0-7-day break (27.8%, n=36) and over 1m5f – 2m (17.2%, n=64). The record reads poorly in Class 2 — 4.3% over 117 runners, 6.3pts below the baseline. 4 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the King George VI And Queen Elizabeth Qipco Stakes at Ascot (Jul 2022, £708,875). The stable star of the record: Caramay (GB) — 8 wins from 39 runs for the yard. Seasonally, the yard fires May–Jul.
Yard patterns
the angles behind the record · vs 10.6% baselineEach tile is the record in that situation vs the 10.6% 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 5 runs (won 1, 1 did not run) · top-rated on KTB Rating in 3 runs (won 0) · fastest on KTB Speed in 2 runs (won 0) · to 28 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.
