Each tile is the record in that situation vs the 0% 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.

Fair A/E per band is the tell: near 1.00 the market had it priced right; well above, the wins came where the market didn't expect them.

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 3 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 3 horses listed, 2 arrived from another yard in our archive; 1 had its first archived run for this yard.

None of them has a 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.

Great Pretender (IRE) 0% · 0–2

Progeny have won 9.2% of 2,800 runs since 2008 (229 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 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 Mary Sanderson's strike rate?
Mary Sanderson has won 0 of 8 runners since 2022, a strike rate of 0% (as at 22 October 2026). Figures are computed from our own results archive. A small sample — fewer than 30 runners, so read the count before the percentage.
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 22 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
