Jonjo & A.J. O'Neill
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 70 runners a season, almost all over hurdles and fences, winning with 12% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.93).
The record is strongest at Fontwell (23.8%, n=42), clear of the yard's 12.4% baseline. It is weakest at Stratford (3.3% over 30 runners) — the widest gap in the record. Debutants struggle at 4.6% (n=65, Fair A/E 0.42). Jonjo O'Neill Jr rides 52% of the entries and edges the yard's average (15% vs 12.4%, A/E 1.00) — the market has that partnership priced right. The record reads poorly in NH Flat races — 4.6% over 65 runners, 7.8pts below the baseline. The market has consistently overbet the yard in Class 2: Fair A/E 0.71 across 139 runners (7.2% strike, −80.12 to a £1 stake) — runners there underperform what the price implies. 5 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Trustmarque Ultima Handicap Chase at Cheltenham (Mar 2026, £84,405). The stable star of the record: Wilful (IRE) — 6 wins from 13 runs for the yard. Seasonally, the yard fires Aug–Oct.
Yard patterns
the angles behind the record · vs 12.4% baselineEach tile is the record in that situation vs the 12.4% 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 8 Oct 2026: the KTB Selection in 12 runs (won 2, 1 did not run) · top-rated on KTB Rating in 11 runs (won 2, 1 did not run) · fastest on KTB Speed in 8 runs (won 2) · to 4 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.
