Derek Haydn Jones
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%".
Sent out around 100 runners a season, almost all on the flat, winning with 7% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.93).
Debutants struggle at 0% (n=32, Fair A/E 0.00). The market has consistently overbet horses returning fresh after 61+ days: 3% strike, Fair A/E 0.53 and −28.00 to a £1 stake over 100 runners — those runners underperformed what the price implied. Dane O'Neill rode 17% of the entries and edges the yard's average (10.4% vs 7%, A/E 1.35) — the partnership beats the margin-free market read. The yard also read well off a 0-7-day break (13.7%, n=51) and off a 8-14-day break (11.8%, n=170). The record read poorly off a 31-60-day break — 2.7% over 149 runners, 4.3pts below the baseline. One Group or Graded win sits in the archive record — the biggest prize the yard has landed: the Betfred Quebec Stakes at Lingfield (AW) (Dec 2011, £17,013). The stable star of the record was Tinshu (IRE) — 10 wins from 84 runs for the yard. Seasonally, the yard fired Jul–Aug.
Yard patterns
the angles behind the record · vs 7% baselineEach tile is the record in that situation vs the 7% baseline — descriptive splits with the sample always shown, not tips. 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.
