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

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

All 14 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 14 horses listed, 9 arrived from another yard in our archive; 5 had their 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.

Only 1 runners in the last 14 days — too few to read against the baseline (gate: n≥15). The card states the sample and stays neutral.

A flat yard: the season runs Mar–Oct. Muted months are small samples (under 30 runs) — read them with the caution they deserve.

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 4 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.

Quick answers

What is J Calderon's strike rate?
J Calderon has won 0 of 32 runners since 2008, a strike rate of 0% (as at 4 November 2026). Figures are computed from our own results archive.
Is J Calderon in form?
Too few runners in the last 14 days to read — 1 runner, which is not a sample we will draw a conclusion from.
What is J Calderon's Fair A/E?
0.00, from 32 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 4 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
