Each tile is the record in that situation vs the 4.8% 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.

Rows below n=30 are shown faded — a small sample is a fact, not a trend. Every figure carries its N.

All 13 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 13 horses listed, 12 arrived from another yard in our archive, most often from J-P Dubois (2) and Mlle L Kneip (2); 1 had its first archived run for this yard.

5 have since run for another yard, most often for Bart De Koninck (2); 8 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 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.

Quick answers

What is B Maes's strike rate?
B Maes has won 2 of 42 runners since 2008, a strike rate of 4.8% (as at 29 October 2026). Figures are computed from our own results archive.
What is B Maes's Fair A/E?
1.12, from 42 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 29 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
