KTB Yard Profile

Sends out around 10 runners a season, almost all over hurdles and fences, winning with 7% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.86).

Deterministic profile computed from 103 archived runs (lifetime window) · updated 1 Nov 2026
KTB at a glance Bryan Carver: 7.6% from 66
The read

Bryan Carver rides 64% of the entries and matches the yard's average almost exactly (7.6%, A/E 0.81). The yard also reads well in Chase races (14.6%, n=48) and over 2m1f – 2m4f (12.5%, n=40). The record reads poorly in Hurdle races — 0% over 52 runners, 6.8pts below the baseline.

Each tile is the record in that situation vs the 6.8% 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.

All 26 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 26 horses listed, 15 arrived from another yard in our archive, most often from Dan Skelton (3) and Jackie Du Plessis (3); 11 had their first archived run for this yard.

4 have since run for another yard, most often for Mrs E Summersby (2); 22 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.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 1 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.

KTB’s figures

the forward record · since 5 Oct 2026

KTB’s figures on this yard’s runners since 10 Oct 2026: the KTB Selection in 2 runs (won 0) · top-rated on KTB Rating in 1 run (won 0) · fastest on KTB Speed in 2 runs (won 0, 1 did not run) · to 28 Oct 2026.

Each pick was a KTB figure’s choice before the off — the published KTB Selection, the top-rated horse on KTB Rating, the fastest on KTB Speed — settled against the result the next morning and never worked out again; “did not run” is counted apart. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.

Quick answers

What is Dean Summersby's strike rate?
Dean Summersby has won 7 of 103 runners since 2008, a strike rate of 6.8% (as at 1 November 2026). Figures are computed from our own results archive.
Who rides most for Dean Summersby?
Bryan Carver, with 66 runners since 2008 — 64% of the total. That pairing has won 5 (7.6%).
Is Dean Summersby in form?
Too few runners in the last 14 days to read — 2 runners, which is not a sample we will draw a conclusion from.
What is Dean Summersby's Fair A/E?
0.86, from 103 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 1 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
