Jonathan Portman
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 9% of them — level with the margin-free market read across the lifetime window (Fair A/E 0.99). In Group and Graded company the record reads 11% (97 runs).
Debutants struggle at 4.3% (n=414, Fair A/E 1.37). Rob Hornby rides 21% of the entries and matches the yard's average almost exactly (10.3%, A/E 1.06) — the partnership beats the margin-free market read. The record reads poorly in Hurdle races — 1.8% over 166 runners, 6.9pts below the baseline. 11 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Weatherbys Super Sprint at Newbury (Jul 2016, £122,925). The stable star of the record: Russian Rumour (IRE) — 10 wins from 64 runs for the yard. Seasonally, the yard fires Jun–Jul.
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 2 runs (won 0) · top-rated on KTB Rating in 3 runs (won 0) · fastest on KTB Speed in 5 runs (won 1, 1 did not run) · to 2 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.
