William Cox
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 4% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.82). Riding last-time-out winners the record reads 10% (52 rides).
The record is strongest at Chepstow (9.8%, n=102) and Salisbury (10%, n=40) — all clear of the rider's 4.2% baseline. It is weakest at Southwell (AW) (0% over 53 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 9.6% (n=52, Fair A/E 0.88). The market has consistently overbet horses returning fresh after 61+ days: 2.1% strike, Fair A/E 0.54 and −44.00 to a £1 stake over 188 rides — those runners underperform what the price implies. Archie Watson supplies 11% of the rides and matches the rider's average almost exactly (4%, A/E 0.75). The rider also reads well on Good to Firm going (8.4%, n=202). The standout partner of the record: Glamorous Breeze (GB) — 5 wins from 26 rides together. Seasonally, the rider fires Jul–Aug.
Riding patterns
the angles behind the record · vs 4.2% baselineEach tile is the record in that situation vs the 4.2% 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 William Cox's strike rate?
- William Cox has won 46 of 1,096 rides since 2022, a strike rate of 4.2% (as at 20 October 2026). Figures are computed from our own results archive.
- Which course does William Cox do best at?
- Salisbury by strike rate: 4 wins from 40 rides (10%) 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 William Cox ride most for?
- Archie Watson, with 124 rides since 2022 — 11% of the total. That pairing has won 5 (4%).
- Is William Cox in form?
- Too few rides in the last 14 days to read — 10 rides, which is not a sample we will draw a conclusion from.
- What is William Cox's Fair A/E?
- 0.82, from 1,090 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.
