KTB Yard Profile

Sends out around 10 runners a season, almost all on the flat, winning with 11% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.41). With a claiming rider up the record reads 18% (40 runs).

Deterministic profile computed from 110 archived runs (lifetime window) · updated 27 Oct 2026
KTB at a glance Claiming riders: 17.5%
The read

It is weakest at Deauville (FR) (3.3% over 30 runners) — the largest sample in the record, and the widest gap. Runners with a claiming rider up have been a positive signal at 17.5% (n=40, Fair A/E 2.64), but debutants struggle at 5% (n=40, Fair A/E 0.68). The yard also reads well over 1m2f – 1m4f (19.5%, n=41). The record reads poorly over 6f – 7f — 3.3% over 30 runners, 7.6pts below the baseline.

Written from the figures on this page — every claim carries its sample. Descriptive, not a tip.

Each tile is the record in that situation vs the 10.9% baseline — descriptive splits with the sample always shown, not tips. 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.

All 48 horses sent out in this window. 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.
Where they came from · where they went next

Of the 48 horses listed, 8 arrived from another yard in our archive; 40 had their first archived run for this yard.

20 have since run for another yard, most often for E D'Andigne (3); 28 have no later run for another yard in our archive.

Read from each listed horse's whole archived career (2005 onwards), not only this window, and counted over the horses listed above, not the whole string. “First archived run” means our archive holds nothing earlier, not that the horse was unraced. A horse with no later run elsewhere may still be here, be off the track, or have run somewhere our archive does not cover — none of that is asserted.

Top line: the yard'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 27 Oct 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 J De Mieulle's strike rate?
J De Mieulle has won 12 of 110 runners since 2008, a strike rate of 10.9% (as at 27 October 2026). Figures are computed from our own results archive.
Which course does J De Mieulle do best at?
Deauville (FR) by strike rate: 1 wins from 30 runners (3.3%) 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.
Is J De Mieulle 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 J De Mieulle's Fair A/E?
1.41, from 110 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.
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 27 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
