Oliver Stammers
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%".
Rides around 220 times a season, almost all on the flat, winning on 10% of them — level with the margin-free market read across five seasons (Fair A/E 0.99). Riding last-time-out winners the record reads 16% (125 rides). Rides mostly for Grant Tuer — 53% of rides in the window.
The record is strongest at Wolverhampton (AW) (15.2%, n=99), clear of the rider's 10.2% baseline. It is weakest at York (2.4% over 41 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 16% (n=125, Fair A/E 0.98), but rides in big fields of 14 or more have been a poor signal at 5.9% (n=136, Fair A/E 1.04). Grant Tuer supplies 53% of the rides and matches the rider's average almost exactly (11.1%, A/E 1.00) — the market has that partnership priced right. The rider also reads well off a 0-7-day break (20.8%, n=77). The standout partner of the record: Bellarchi (IRE) — 6 wins from 22 rides together. Seasonally, the rider fires Jun–Jul.
Riding patterns
the angles behind the record · vs 10.2% baselineEach tile is the record in that situation vs the 10.2% 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.

Quick answers
- What is Oliver Stammers's strike rate?
- Oliver Stammers has won 112 of 1,093 rides since 2022, a strike rate of 10.2% (as at 20 October 2026). Figures are computed from our own results archive.
- Which course does Oliver Stammers do best at?
- Wolverhampton (AW) by strike rate: 15 wins from 99 rides (15.2%) since 2022. 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 Oliver Stammers ride most for?
- Grant Tuer, with 575 rides since 2022 — 53% of the total. That pairing has won 64 (11.1%).
- Is Oliver Stammers in form?
- Too few rides in the last 14 days to read — 9 rides, which is not a sample we will draw a conclusion from.
- What is Oliver Stammers's Fair A/E?
- 0.99, from 1,089 rides with a computed fair probability since 2022. 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.
