Archive record 2005–2007
No rides from 1 Jan 2008, where our aggregate statistics normally begin — showing the full archive record instead, 31 Mar 2005 to 28 Jun 2007. Figures that need a horse's earlier runs (debuts, time since a run, first-time headgear, new connections, last-time-out winners) are left out: for runs this early our archive cannot see what came before.

Each tile is the record in that situation vs the 4.3% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. Claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races. Tiles that depend on a horse's earlier runs (debuts, time off, first-time headgear, new connections, last-time-out winners) are not shown on an archive-era record: for runs this early our archive cannot see what came before.

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. On this page the header statistics and this card both count from the archive floor (2005), so they agree.

Top line: the rider'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 2005, as at 6 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 Mrs S Bosley's strike rate?
Mrs S Bosley has won 2 of 47 rides between 2005 and 2007, a strike rate of 4.3% (as at 6 November 2026). Figures are computed from our own results archive. Our archive begins in 2005, so anything earlier is not counted.
What is Mrs S Bosley's Fair A/E?
0.45, from 47 rides with a computed fair probability between 2005 and 2007. 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 6 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008). This profile has no runs from 2008, so every figure on this page counts from the start of the archive instead.
