D. J. Jeffreys
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 50 runners a season, almost all over hurdles and fences, winning with 8% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.90). With a claiming rider up the record reads 10% (202 runs).
The record is strongest at Perth (23.5%, n=34), clear of the yard's 7.7% baseline. It is weakest at Southwell (2.2% over 46 runners) — the widest gap in the record. Debutants struggle at 0% (n=59, Fair A/E 0.00). The market has consistently overbet horses returning fresh after 61+ days: 6.6% strike, Fair A/E 0.84 and −98.91 to a £1 stake over 257 runners — those runners underperform what the price implies. Kielan Woods rides 27% of the entries and matches the yard's average almost exactly (8.4%, A/E 0.86). The yard also reads well in Chase races (12.2%, n=172). The record reads poorly in NH Flat races — 0% over 44 runners, 7.7pts below the baseline. The stable star of the record: Lively Citizen (IRE) — 7 wins from 43 runs for the yard. Seasonally, the yard fires Jun–Aug.
Yard patterns
the angles behind the record · vs 7.7% baselineEach tile is the record in that situation vs the 7.7% 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.

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 D. J. Jeffreys's strike rate?
- D. J. Jeffreys has won 67 of 872 runners since 2008, a strike rate of 7.7% (as at 4 November 2026). Figures are computed from our own results archive.
- Which course does D. J. Jeffreys do best at?
- Perth by strike rate: 8 wins from 34 runners (23.5%) since 2008. 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 D. J. Jeffreys?
- Kielan Woods, with 238 runners since 2008 — 27% of the total. That pairing has won 20 (8.4%).
- Is D. J. Jeffreys in form?
- Too few runners in the last 14 days to read — 1 runner, which is not a sample we will draw a conclusion from.
- What is D. J. Jeffreys's Fair A/E?
- 0.90, from 869 runners 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.
