KTB Yard Profile

Sends out around 60 runners a season, almost all on the flat, winning with 9% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.78). The edge shows sharpest with horses returning fresh: 15% off breaks of two months or more (46 runs).

The read

The record is strongest at Chelmsford City (AW) (13.3%, n=113), clear of the yard's 8.7% baseline. It is weakest at Wolverhampton (AW) (0% over 38 runners) — the widest gap in the record. Horses returning fresh after 61+ days have been a positive signal at 15.2% (n=46, Fair A/E 1.63). Ray Dawson rides 17% of the entries and edges the yard's average (11.5% vs 8.7%, A/E 0.92). The record reads poorly on Good to Firm going — 2.2% over 46 runners, 6.5pts below the baseline. The market has consistently overbet the yard off a 15-30-day break: Fair A/E 0.35 across 126 runners (4% strike, −92.92 to a £1 stake) — runners there underperform what the price implies. The stable star of the record: Herringswell (FR) — 6 wins from 25 runs for the yard.

Each tile is the record in that situation vs the 8.7% 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, 23 arrived from another yard in our archive, most often from Michael J Browne (3) and H-F Devin (2); 25 had their first archived run for this yard.

19 have since run for another yard, most often for Michael Appleby (2) and Simon Pearce (2); 29 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 15 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 Henry Spiller's strike rate?
Henry Spiller has won 27 of 311 runners since 2022, a strike rate of 8.7% (as at 15 October 2026). Figures are computed from our own results archive.
Which course does Henry Spiller do best at?
Chelmsford City (AW) by strike rate: 15 wins from 113 runners (13.3%) since 2022. 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 Henry Spiller?
Ray Dawson, with 52 runners since 2022 — 17% of the total. That pairing has won 6 (11.5%).
What is Henry Spiller's Fair A/E?
0.78, from 310 runners 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 15 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
