Miss Isabel Tompsett
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%".
Rode around 50 times a season, winning on 12% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.13). First rides on a horse are a strength: 17% on the first captured pairing (71 rides). Rode mostly for Bernard Llewellyn — 60% of rides in the window.
First rides on a horse have been a positive signal at 16.9% (n=71, Fair A/E 1.75), but rides in big fields of 14 or more have been a poor signal at 2.1% (n=48, Fair A/E 0.29). Claiming rides are the standout value angle: 12.2% strikes only just above baseline, but Fair A/E 1.16 and +59.25 to a £1 stake over 172 rides — a record the market has persistently underpriced. Bernard Llewellyn supplied 60% of the rides and sits below the rider's average (9.6% vs 12%, A/E 0.90). The rider also read well on Good to Firm going (19.5%, n=41) and on Good to Soft going (19.4%, n=36). The market has also underrated the rider in Class 4: Fair A/E 1.37 across 64 rides (15.6% strike, +1.50 to a £1 stake). The record read poorly on Good going — 7.1% over 56 rides, 4.9pts below the baseline.
Riding patterns
the angles behind the record · vs 12% baselineEach tile is the record in that situation vs the 12% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. First rides are the first captured pairing of horse and rider; last-time-out winners are horses whose previous captured run was a win; claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races.
