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%".
KTB Yard Profile
Sends out around 50 runners a season, almost all over hurdles and fences, winning with 4% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.76).

The read
The record is strongest at Exeter (6.8%, n=59), clear of the yard's 3.5% baseline. Runners with a claiming rider up have been a poor signal at 0% (n=78, Fair A/E 0.00). Bryony Frost rides 23% of the entries and edges the yard's average (7.5% vs 3.5%, A/E 1.44) — the partnership beats the margin-free market read. The yard also reads well off a 15-30-day break (7.1%, n=70) and over 1m5f – 2m (7%, n=57). The stable star of the record: Oscar Bay (IRE) — 7 wins from 25 runs for the yard.

Each tile is the record in that situation vs the 3.5% 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.

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.

Rows below n=30 are shown faded — a small sample is a fact, not a trend. Every figure carries its N.
Chases and hurdles only — bumpers have no obstacles, so completion is not a question there. F fell · UR unseated rider · PU pulled up · BD brought down · Oth covers refusals, slip-ups, run-outs and the rare disqualification. Non-runners are excluded throughout. Rows under n=30 are shown faded. A descriptive record, not a tip.
All 35 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 35 horses listed, 13 arrived from another yard in our archive; 22 had their first archived run for this yard.
7 have since run for another yard, most often for Robert Walford (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.

In our archive from its very first year (2005), so this career almost certainly began earlier than our record does. The figures above count 2005 onwards only — what the archive holds, not a full-career total. This card is the full archive census (2005→); the statistics in the header aggregate from 2008 — the floor that guarantees every horse a complete captured career — so this card can legitimately show more wins than the header.
Oscar Bay (IRE) — toteexacta Beginners' Chase Haydock · May 2008 · Class 2
Progeny have won 5.1% of 351 runs since 2008 (30 horses).
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 20 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.
The record
latest 50 of 2,189 · newest first
The latest 50 of 2,189 archived runners, newest first. The full record runs from 3 January 2005 to 18 September 2026.
Drawn from the whole archive (2005 onwards), so it can include runs outside the window the header statistics cover. Non-runners are not listed. A finish shown in letters is a non-completion (F fell · UR unseated · PU pulled up · BD brought down).
Quick answers
What is Jimmy Frost's strike rate?
Jimmy Frost has won 8 of 230 runners since 2022, a strike rate of 3.5% (as at 20 October 2026). Figures are computed from our own results archive.
Which course does Jimmy Frost do best at?
Exeter by strike rate: 4 wins from 59 runners (6.8%) 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 Jimmy Frost?
Bryony Frost, with 53 runners since 2022 — 23% of the total. That pairing has won 4 (7.5%).
What is Jimmy Frost's Fair A/E?
0.76, from 230 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.
