Alan Dempsey
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 579 times in our archive record (2005–2007), almost all over hurdles and fences, winning on 5% of them — a touch below the margin-free market read across that record (Fair A/E 0.83).
The record is strongest at Ayr (11.8%, n=34) and Carlisle (11.1%, n=36) — all clear of the rider's 5.2% baseline. Rides in big fields of 14 or more have been a poor signal at 1.9% (n=211, Fair A/E 0.47). Howard Johnson supplied 11% of the rides and edges the rider's average (7.7% vs 5.2%, A/E 0.97) — the market has that partnership priced right. The rider also read well on Heavy going (10.5%, n=86). The record read poorly in NH Flat races — 0% over 46 rides, 5.2pts below the baseline. Seasonally, the rider fired Feb–Mar.
Riding patterns
the angles behind the record · vs 5.2% baselineEach tile is the record in that situation vs the 5.2% baseline — descriptive splits with the sample always shown, not tips. Tiles under 30 runs render muted. Claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races. Tiles that depend on a horse's earlier runs (debuts, time off, first-time headgear, new connections, last-time-out winners) are not shown on an archive-era record: for runs this early our archive cannot see what came before.

Quick answers
- What is Alan Dempsey's strike rate?
- Alan Dempsey has won 30 of 579 rides between 2005 and 2007, a strike rate of 5.2% (as at 28 October 2026). Figures are computed from our own results archive. Our archive begins in 2005, so anything earlier is not counted.
- Which course does Alan Dempsey do best at?
- Ayr by strike rate: 4 wins from 34 rides (11.8%) between 2005 and 2007. 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 Alan Dempsey ride most for?
- Howard Johnson, with 65 rides between 2005 and 2007 — 11% of the total. That pairing has won 5 (7.7%).
- What is Alan Dempsey's Fair A/E?
- 0.83, from 578 rides with a computed fair probability between 2005 and 2007. 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.
