KTB Rider Profile

Rides around 50 times a season, almost all on the flat, winning on 9% of them — beating the margin-free market read across five seasons (Fair A/E 1.37). First rides on a horse are a strength: 11% on the first captured pairing (131 rides).

The read

Rides in big fields of 14 or more have been a poor signal at 2.9% (n=140, Fair A/E 0.58). First rides on a horse are the standout value angle: 10.7% strikes only just above baseline, but Fair A/E 1.74 and +4.40 to a £1 stake over 131 rides — a record the market has persistently underpriced. S Wattel supplies 37% of the rides and edges the rider's average (11.5% vs 8.8%, A/E 1.46) — the partnership beats the margin-free market read. The rider also reads well on Good to Soft going (16.7%, n=30).

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 8.8% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. First rides are the first captured pairing of horse and rider; last-time-out winners are horses whose previous captured run was a win; claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races.

Descriptive splits ranked by divergence × sample — insight, not instruction. Every angle carries its N; nothing under 30 runs qualifies. Rows within 2pts of the baseline appear only when the market-relative read (Fair A/E) diverges, and show it.

Showing the 60 most-raced of the 147 horses ridden in this window — each ran at least 1 time. Horses with fewer runs aren't listed; search finds any horse since 2005. 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.

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 2008, as at 15 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 Mme Alison Massin's strike rate?
Mme Alison Massin has won 23 of 260 rides since 2022, a strike rate of 8.8% (as at 15 November 2026). Figures are computed from our own results archive.
Which course does Mme Alison Massin do best at?
Chantilly (FR) by strike rate: 7 wins from 72 rides (9.7%) since 2022. Read from the 15 courses with the most rides 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.
Which yard does Mme Alison Massin ride most for?
S Wattel, with 96 rides since 2022 — 37% of the total. That pairing has won 11 (11.5%).
What is Mme Alison Massin's Fair A/E?
1.37, from 260 rides with a computed fair probability since 2022. 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.
