KTB Rider Profile

Rides around 70 times a season, almost all on the flat, winning on 3% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.59).

The read

The record is strongest at Longchamp (FR) (6.4%, n=47), clear of the rider's 3.4% baseline. The market has consistently overbet first rides on a horse: 1.4% strike, Fair A/E 0.31 and −132.50 to a £1 stake over 145 rides — those runners underperform what the price implies. N Caullery supplies 21% of the rides and matches the rider's average almost exactly (4.2%, A/E 0.57). The record reads poorly off a 8-14-day break — 0% over 45 rides, 3.4pts below the baseline. 15 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Prix de Ris-Orangis at Deauville (FR) (Jul 2008, £29,412). The standout partner of the record: Huangdi (FR) — 5 wins from 16 rides together.

Each tile is the record in that situation vs the 3.4% 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.

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. This card is the full archive census (2005→); the statistics in the header aggregate from 2008 — the floor that guarantees every horse a complete captured career — so this card can legitimately show more wins than the header.

Quick answers

What is Sebastien Maillot's strike rate?
Sebastien Maillot has won 12 of 348 rides since 2022, a strike rate of 3.4% (as at 6 November 2026). Figures are computed from our own results archive.
Which course does Sebastien Maillot do best at?
Longchamp (FR) by strike rate: 3 wins from 47 rides (6.4%) 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 Sebastien Maillot ride most for?
N Caullery, with 72 rides since 2022 — 21% of the total. That pairing has won 3 (4.2%).
What is Sebastien Maillot's Fair A/E?
0.59, from 345 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. Figures as at 6 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
