Nerys Dutfield
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 40 runners a season, across both codes, winning with 4% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.69).
The market has consistently overbet runners with a claiming rider up: 5% strike, Fair A/E 0.70 and −64.50 to a £1 stake over 139 runners — those runners underperformed what the price implied. Jack Mitchell rode 25% of the entries and beats the yard's average (13.6% vs 4.2%, A/E 1.52) — the partnership beats the margin-free market read. The yard also read well over 6f – 7f (8.9%, n=56) and off a break of 180+ days (7.9%, n=38). The record read poorly in Hurdle races — 0% over 69 runners, 4.2pts below the baseline. The stable star of the record was Bold Argument (IRE) — 5 wins from 47 runs for the yard. Seasonally, the yard fired May–Jun.
Yard patterns
the angles behind the record · vs 4.2% baselineEach tile is the record in that situation vs the 4.2% 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.
