KTB Rider Profile

The read

It is weakest at Saint-Cloud (FR) (3.3% over 60 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 13.2% (n=38, Fair A/E 0.91), but in Group and Graded company the record reads poorly at 0% (n=36, Fair A/E 0.00). The market has consistently overbet horses returning fresh after 61+ days: 5.8% strike, Fair A/E 0.72 and −82.80 to a £1 stake over 155 rides — those runners underperformed what the price implied. Y-M Porzier supplied 27% of the rides and edges the rider's average (12.9% vs 8.3%, A/E 1.24) — the partnership beats the margin-free market read. The record read poorly on Good to Soft going — 0% over 48 rides, 8.3pts below the baseline.

Each tile is the record in that situation vs the 8.3% baseline — descriptive splits with the sample always shown, not tips. 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.

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 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 Stevan Bourgois's strike rate?
Stevan Bourgois has won 47 of 564 rides since 2008, a strike rate of 8.3% (as at 29 October 2026). Figures are computed from our own results archive.
Which course does Stevan Bourgois do best at?
Enghien (FR) by strike rate: 10 wins from 86 rides (11.6%) since 2008. 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 Stevan Bourgois ride most for?
Y-M Porzier, with 155 rides since 2008 — 27% of the total. That pairing has won 20 (12.9%).
What is Stevan Bourgois's Fair A/E?
1.03, from 528 rides 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.
