Sir Mark Prescott Bt
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 250 runners a season, almost all on the flat, winning with 17% 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: 29% off breaks of two months or more (189 runs). The yard is quiet just now — 2 winners in the last fortnight, below its own baseline.
Horses returning fresh after 61+ days have been a positive signal at 28.6% (n=189, Fair A/E 1.35), but debutants struggle at 4.9% (n=143, Fair A/E 0.79). Right now the yard is in a quiet spell: 2 from 19 runners in the last 14 days (10.5%, 6.7pts below the 17.2% baseline). Luke Morris rides 62% of the entries and matches the yard's average almost exactly (16.7%, A/E 0.95). The yard also reads well in Class 6 (31.9%, n=166) and off a 61-180-day break (31.9%, n=72). The record reads poorly over 6f – 7f — 9.1% over 363 runners, 8.1pts below the baseline. 47 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Qatar Prix de l'Arc de Triomphe at Longchamp (FR) (Oct 2022, £2,400,840). The stable star of the record: Don't Be (GB) — 8 wins from 18 runs for the yard. Seasonally, the yard fires May–Aug.
Yard patterns
the angles behind the record · vs 17.2% baselineEach tile is the record in that situation vs the 17.2% 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 6 Oct 2026: the KTB Selection in 5 runs (won 2) · top-rated on KTB Rating in 2 runs (won 0) · fastest on KTB Speed in 2 runs (won 0) · to 30 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.
