KTB Rider Profile

Rode around 80 times a season, winning on 10% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.17). Riding last-time-out winners the record reads 14% (59 rides).

The read

It is weakest at Curragh (2.1% over 47 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 13.6% (n=59, Fair A/E 1.09), but horses returning fresh after 61+ days have been a poor signal at 4.4% (n=90, Fair A/E 0.83). M Halford supplied 11% of the rides and sits below the rider's average (7.2% vs 9.8%, A/E 0.70). The rider also read well in Class 4 (16%, n=50). The record read poorly off a 61-180-day break — 3.2% over 62 rides, 6.6pts below the baseline. The market has consistently overbet the rider on Good to Firm going: Fair A/E 0.41 across 86 rides (3.5% strike, −66.25 to a £1 stake) — runners there underperformed what the price implied. Seasonally, the rider fired Jul–Sep.

Each tile is the record in that situation vs the 9.8% 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.

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.

Top line: the rider's own record with each sire's runners (win %, wins–runs), same window as the header; faded under 30 runs. Beneath it: every run by that sire's progeny in our archive since 2008, as at 6 Nov 2026 — what they have done, not a forecast. A going or a distance is named only where at least 100 progeny runs sit 3 or more points from the sire's own win rate. Distance bands cover Flat and jumps together.

Quick answers

What is Sean Corby's strike rate?
Sean Corby has won 61 of 620 rides since 2008, a strike rate of 9.8% (as at 6 November 2026). Figures are computed from our own results archive.
Which course does Sean Corby do best at?
Gowran Park by strike rate: 4 wins from 30 rides (13.3%) 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 Sean Corby ride most for?
M Halford, with 69 rides since 2008 — 11% of the total. That pairing has won 5 (7.2%).
What is Sean Corby's Fair A/E?
1.17, from 618 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.
