David Dennis
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, winning with 10% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.92). With a claiming rider up the record reads 13% (337 runs).
The record is strongest at Newbury (21.9%, n=32), clear of the yard's 9.6% baseline. Runners with a claiming rider up have been a positive signal at 13.1% (n=337, Fair A/E 1.21), but in Group and Graded company the record reads poorly at 0% (n=34, Fair A/E 0.00). The market has consistently overbet debutants: 2% strike, Fair A/E 0.36 and −41.00 to a £1 stake over 101 runners — those runners underperform what the price implies. Aidan Coleman rides 11% of the entries and matches the yard's average almost exactly (8%, A/E 0.67). The yard also reads well off a 0-7-day break (23%, n=87). The record reads poorly in Class 1 — 0% over 38 runners, 9.6pts below the baseline. The stable star of the record: Flying Verse (GB) — 10 wins from 53 runs for the yard. Seasonally, the yard fires May–Jun.
Yard patterns
the angles behind the record · vs 9.6% baselineEach tile is the record in that situation vs the 9.6% 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.

Quick answers
- What is David Dennis's strike rate?
- David Dennis has won 199 of 2,070 runners since 2008, a strike rate of 9.6% (as at 3 November 2026). Figures are computed from our own results archive.
- Which course does David Dennis do best at?
- Market Rasen by strike rate: 14 wins from 82 runners (17.1%) 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 David Dennis?
- Aidan Coleman, with 237 runners since 2008 — 11% of the total. That pairing has won 19 (8%).
- Is David Dennis in form?
- Too few runners in the last 14 days to read — 4 runners, which is not a sample we will draw a conclusion from.
- What is David Dennis's Fair A/E?
- 0.92, from 2,067 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.
