Each tile is the record in that situation vs the 0% 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.

Fair A/E per band is the tell: near 1.00 the market had it priced right; well above, the wins came where the market didn't expect them.

Chases and hurdles only — bumpers have no obstacles, so completion is not a question there. F fell · UR unseated rider · PU pulled up · BD brought down · Oth covers refusals, slip-ups, run-outs and the rare disqualification. Non-runners are excluded throughout. Rows under n=30 are shown faded. A descriptive record, not a tip.

Sires of the horses ridden

progeny record · win % by ground and trip
Jeremy (USA) 0% · 0–14
Progeny have won 11.2% of 6,725 runs since 2011 (425 horses). Weakest on Standard (AW) going: 7.5% from 664. Strongest beyond 3m (all codes): 16.3% from 147. Weakest over 6f – 7f (all codes): 7.8% from 743.
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 5 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 Mr David O'Brien's strike rate?
Mr David O'Brien has won 0 of 14 rides since 2022, a strike rate of 0% (as at 5 November 2026). Figures are computed from our own results archive. A small sample — fewer than 30 rides, so read the count before the percentage.
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. Figures as at 5 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
