Jim & Suzi Best
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%".
Sends out around 110 runners a season, across both codes, winning with 9% of them — level with the margin-free market read across five seasons (Fair A/E 1.01). With a claiming rider up the record reads 16% (69 runs).
The record is strongest at Chelmsford (AW) (15%, n=60), clear of the yard's 8.6% baseline. It is weakest at Lingfield (AW) (2.8% over 106 runners) — the largest sample in the record, and the widest gap. Runners with a claiming rider up have been a positive signal at 15.9% (n=69, Fair A/E 1.44), but a horse having headgear put back on after a bare run has been a poor signal at 5.4% (n=37, Fair A/E 0.71). Luke Morris rides 11% of the entries and matches the yard's average almost exactly (7.1%, A/E 0.71). The yard also reads well off a 0-7-day break (21.2%, n=52) and on Good going (14%, n=93). The stable star of the record: My Boy Harry (GB) — 5 wins from 35 runs for the yard. Seasonally, the yard fires Oct–Nov.
Yard patterns
the angles behind the record · vs 8.6% baselineEach tile is the record in that situation vs the 8.6% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. Headgear figures use the true-first definition (first gear appearance in the captured career); returns are gear back on after a bare run. Claiming riders are runs where the booked rider carried a weight claim. Group / Graded covers pattern and listed races. The same beliefs, tested across every yard and every GB and Irish race since 2005: Racing myths.

the forward record · since 5 Oct 2026KTB’s figures on this yard’s runners since 13 Oct 2026: the KTB Selection in 1 run (won 0, 1 did not run) · fastest on KTB Speed in 1 run (won 0, 1 did not run) · to 13 Oct 2026.
Each pick was a KTB figure’s choice before the off — the published KTB Selection, the top-rated horse on KTB Rating, the fastest on KTB Speed — settled against the result the next morning and never worked out again; “did not run” is counted apart. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.
Quick answers
- What is Jim & Suzi Best's strike rate?
- Jim & Suzi Best has won 45 of 525 runners since 2022, a strike rate of 8.6% (as at 3 November 2026). Figures are computed from our own results archive.
- Which course does Jim & Suzi Best do best at?
- Chelmsford (AW) by strike rate: 9 wins from 60 runners (15%) since 2022. Read from the 15 courses with the most runners 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.
- Who rides most for Jim & Suzi Best?
- Luke Morris, with 56 runners since 2022 — 11% of the total. That pairing has won 4 (7.1%).
- Is Jim & Suzi Best in form?
- Too few runners in the last 14 days to read — 13 runners, which is not a sample we will draw a conclusion from.
- What is Jim & Suzi Best's Fair A/E?
- 1.01, from 523 runners 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.
