KTB Rider Profile

Rides around 100 times a season, almost all over hurdles and fences, winning on 7% of them — level with the margin-free market read across five seasons (Fair A/E 0.98). Riding last-time-out winners the record reads 13% (40 rides).

KTB at a glance Gavin Cromwell: 8.5% from 153 LTO winners: 12.5%
The read

The record is strongest at Naas (12.5%, n=40), clear of the rider's 6.6% baseline. Rides on last-time-out winners have been a positive signal at 12.5% (n=40, Fair A/E 1.00). Gavin Cromwell supplies 32% of the rides and matches the rider's average almost exactly (8.5%, A/E 0.95). The rider also reads well off a 31-60-day break (12.1%, n=124). The record reads poorly on Heavy going — 0% over 81 rides, 6.6pts below the baseline. The market has consistently overbet the rider over 2m5f – 3m: Fair A/E 0.50 across 94 rides (3.2% strike, −70.17 to a £1 stake) — runners there underperform what the price implies. 17 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Thetote.com Galway Plate at Galway (Jul 2019, £177,000). The standout partner of the record: Dinnie's Vinnie (IRE) — 7 wins from 22 rides together.

Each tile is the record in that situation vs the 6.6% 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.

Runs, wins and places only: a strike rate or a return on a handful of runs is noise, so none is quoted per horse — each horse's full record is on its own page.

Top line: the rider's own record with each sire's runners (win %, wins–runs), same window as the header; faded under 30 runs. Beneath it: every run by that sire's progeny in our archive since 2008, as at 11 Nov 2026 — what they have done, not a forecast. A going or a distance is named only where at least 100 progeny runs sit 3 or more points from the sire's own win rate. Distance bands cover Flat and jumps together.

Quick answers

What is L P Dempsey's strike rate?
L P Dempsey has won 32 of 485 rides since 2022, a strike rate of 6.6% (as at 11 November 2026). Figures are computed from our own results archive.
Which course does L P Dempsey do best at?
Naas by strike rate: 5 wins from 40 rides (12.5%) since 2022. 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 L P Dempsey ride most for?
Gavin Cromwell, with 153 rides since 2022 — 32% of the total. That pairing has won 13 (8.5%).
What is L P Dempsey's Fair A/E?
0.98, from 485 rides 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.
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%". Three sample sizes are reported and never blended: runs (n), the ROI basis (n at SP), and the fair-A/E basis (n with a computed fair probability).

Strike rate is wins over all runs (n). ROI is £1 level stakes at SP over runs with a parseable price (n at SP). Fair A/E is wins over margin-stripped market expectation, over runs with a computed fair probability (n fair). The three Ns can legitimately differ and are always shown. Figures as at 11 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
