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 10 runners a season, winning with 7% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.89).

KTB at a glanceTom O'Brien: 9.4% from 85
The read
The record is strongest at Plumpton (9.6%, n=83), clear of the yard's 6.5% baseline. It is weakest at Fontwell (2.9% over 68 runners) — the widest gap in the record. The market has consistently overbet horses returning fresh after 61+ days: 3.8% strike, Fair A/E 0.74 and −69.50 to a £1 stake over 105 runners — those runners underperform what the price implies. Tom O'Brien rides 30% of the entries and edges the yard's average (9.4% vs 6.5%, A/E 0.84). The yard also reads well on Heavy going (13.5%, n=37) and in Class 5 (9.9%, n=121).
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 6.5% 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.

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 45 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 45 horses listed, 19 arrived from another yard in our archive, most often from Joseph Patrick O'Brien (3) and Dan Skelton (2); 26 had their first archived run for this yard.
8 have since run for another yard, most often for Marie Martin (5); 37 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.

Best season · 4 wins
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.

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 29 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

The latest 50 of 295 archived runners, newest first. The full record runs from 13 March 2005 to 19 October 2023.
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 Michael Roberts's strike rate?
Michael Roberts has won 18 of 279 runners since 2008, a strike rate of 6.5% (as at 29 October 2026). Figures are computed from our own results archive.
Which course does Michael Roberts do best at?
Plumpton by strike rate: 8 wins from 83 runners (9.6%) 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 Michael Roberts?
Tom O'Brien, with 85 runners since 2008 — 30% of the total. That pairing has won 8 (9.4%).
What is Michael Roberts's Fair A/E?
0.89, from 278 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.
