KTB Rider Profile

Rode around 20 times a season, almost all over hurdles and fences, winning on 6% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.74). The edge shows sharpest with horses returning fresh: 9% off breaks of two months or more (47 runs). Rode mostly for F-M Cottin — 62% of rides in the window.

The read

Horses returning fresh after 61+ days have been a positive signal at 8.5% (n=47, Fair A/E 1.42). The market has consistently overbet first rides on a horse: 4.9% strike, Fair A/E 0.68 and −49.00 to a £1 stake over 102 rides — those runners underperformed what the price implied. F-M Cottin supplied 62% of the rides and matches the rider's average almost exactly (7.1%, A/E 0.85). The rider also read well off a 61-180-day break (9.7%, n=31). The record read poorly off a 8-14-day break — 2.4% over 42 rides, 3.1pts below the baseline.

Each tile is the record in that situation vs the 5.5% baseline — descriptive splits with the sample always shown, not tips. 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.

Showing the 60 most-raced of the 102 horses ridden in this window — each ran at least 1 time. Horses with fewer runs aren't listed; search finds any horse since 2005. Runs, wins and places only: a strike rate or a return on a handful of runs is noise, so none is quoted per horse — each horse's full record is on its own page.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 28 Oct 2026 — what they have done, not a forecast.

Quick answers

What is David Brassil's strike rate?
David Brassil has won 10 of 183 rides since 2008, a strike rate of 5.5% (as at 28 October 2026). Figures are computed from our own results archive.
Which course does David Brassil do best at?
Auteuil (FR) by strike rate: 6 wins from 119 rides (5%) since 2008. Read from the 15 courses with the most rides on the same basis, and only those with at least 30 — a small sample cannot top the list, and a rarely-visited course is not in the comparison.
Which yard does David Brassil ride most for?
F-M Cottin, with 113 rides since 2008 — 62% of the total. That pairing has won 8 (7.1%).
What is David Brassil's Fair A/E?
0.74, from 180 rides with a computed fair probability since 2008. Fair A/E compares actual wins with a margin-stripped market expectation, so 1.00 is par: above it the wins came at bigger prices than the margin-free market implied, below it they did not.
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%". Three sample sizes are reported and never blended: runs (n), the ROI basis (n at SP), and the fair-A/E basis (n with a computed fair probability).

Strike rate is wins over all runs (n). ROI is £1 level stakes at SP over runs with a parseable price (n at SP). Fair A/E is wins over margin-stripped market expectation, over runs with a computed fair probability (n fair). The three Ns can legitimately differ and are always shown.
