KTB Yard Profile

Sent out around 50 runners a season, almost all on the flat, winning with 5% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.84).

Deterministic profile computed from 316 archived runs (lifetime window) · updated 22 Oct 2026
KTB at a glance Nicky Mackay: 3.8% from 52 Claiming riders: 5.7%
The read

It is weakest at Lingfield (AW) (1.8% over 55 runners) — the widest gap in the record. Horses returning fresh after 61+ days have been a poor signal at 0% (n=34, Fair A/E 0.00). Nicky Mackay rode 16% of the entries and matches the yard's average almost exactly (3.8%, A/E 0.58). The market has consistently overbet the yard in Class 5: Fair A/E 0.48 across 105 runners (2.9% strike, −24.75 to a £1 stake) — runners there underperformed what the price implied.

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 5.1% 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 44 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 44 horses listed, 28 arrived from another yard in our archive, most often from Terry Clement (3) and Julia Feilden (2); 16 had their first archived run for this yard.

21 have since run for another yard, most often for Michael Wigham (3) and Terry Clement (2); 23 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 22 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 Mark Rimmer's strike rate?
Mark Rimmer has won 16 of 316 runners since 2008, a strike rate of 5.1% (as at 22 October 2026). Figures are computed from our own results archive.
Which course does Mark Rimmer do best at?
Yarmouth by strike rate: 5 wins from 65 runners (7.7%) 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 Mark Rimmer?
Nicky Mackay, with 52 runners since 2008 — 16% of the total. That pairing has won 2 (3.8%).
What is Mark Rimmer's Fair A/E?
0.84, from 314 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.
