Rosie Jessop
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%".
Rode around 40 times a season, almost all on the flat, winning on 11% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.13). Riding last-time-out winners the record reads 37% (59 rides).
The record is strongest at Yarmouth (19.1%, n=47), clear of the rider's 11.2% baseline. Rides on last-time-out winners have been a positive signal at 37.3% (n=59, Fair A/E 1.55), but rides in big fields of 14 or more have been a poor signal at 4.9% (n=61, Fair A/E 0.86). Peter Charalambous supplied 23% of the rides and edges the rider's average (15.3% vs 11.2%, A/E 1.54) — the partnership beats the margin-free market read. The rider also read well off a 0-7-day break (18.8%, n=64) and over 1m2f – 1m4f (16.6%, n=151). The standout partner of the record was Boonga Roogeta (GB) — 8 wins from 24 rides together.
Riding patterns
the angles behind the record · vs 11.2% baselineEach tile is the record in that situation vs the 11.2% 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.

Quick answers
- What is Rosie Jessop's strike rate?
- Rosie Jessop has won 55 of 490 rides since 2008, a strike rate of 11.2% (as at 6 November 2026). Figures are computed from our own results archive.
- Which course does Rosie Jessop do best at?
- Yarmouth by strike rate: 9 wins from 47 rides (19.1%) 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 Rosie Jessop ride most for?
- Peter Charalambous, with 111 rides since 2008 — 23% of the total. That pairing has won 17 (15.3%).
- What is Rosie Jessop's Fair A/E?
- 1.13, from 486 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.
