KTB Yard Profile

Sends out around 20 runners a season, across both codes, winning with 6% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.87). Horses with headgear back on after a bare run strike at 8% (37 runs).

The read

The record is strongest at Plumpton (14%, n=50), clear of the yard's 6.1% baseline. It is weakest at Lingfield (AW) (2.1% over 48 runners) — the widest gap in the record. The market has consistently overbet horses returning fresh after 61+ days: 4.5% strike, Fair A/E 0.72 and −38.00 to a £1 stake over 110 runners — those runners underperform what the price implies. Daryl Jacob rides 14% of the entries and edges the yard's average (9.6% vs 6.1%, A/E 1.05) — the partnership beats the margin-free market read. The yard also reads well on Soft going (13.9%, n=36) and over 2m1f – 2m4f (10.2%, n=59). The record reads poorly in Class 6 — 2.5% over 119 runners, 3.6pts below the baseline. The market has consistently overbet the yard in Flat races: Fair A/E 0.65 across 178 runners (3.4% strike, −128.38 to a £1 stake) — runners there underperform what the price implies.

Each tile is the record in that situation vs the 6.1% 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.

This filter uses derived form angles computed for 8.4% of the archive so far (as at 8 Nov 2026); the sample will grow as sequencing completes.
Descriptive splits ranked by divergence × sample — insight, not instruction. Every angle carries its N; nothing under 30 runs qualifies. Rows within 2pts of the baseline appear only when the market-relative read (Fair A/E) diverges, and show it.

All 49 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 49 horses listed, 38 arrived from another yard in our archive, most often from Jim Best (15) and Gordon Elliott (2); 11 had their first archived run for this yard.

19 have since run for another yard, most often for Jim & Suzi Best (9) and Emma Owen (5); 30 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 8 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 Suzi Best's strike rate?
Suzi Best has won 23 of 376 runners since 2008, a strike rate of 6.1% (as at 8 November 2026). Figures are computed from our own results archive.
Which course does Suzi Best do best at?
Plumpton by strike rate: 7 wins from 50 runners (14%) 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 Suzi Best?
Daryl Jacob, with 52 runners since 2008 — 14% of the total. That pairing has won 5 (9.6%).
What is Suzi Best's Fair A/E?
0.87, from 376 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 8 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
