KTB Rider Profile

Rides around 20 times a season, almost all on the flat, winning on 7% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.93). Rides mostly for Scott Dixon — 70% of rides in the window.

The read

Scott Dixon supplies 70% of the rides and matches the rider's average almost exactly (6.4%, A/E 1.01) — the market has that partnership priced right. The market has also underrated the rider over 6f – 7f: Fair A/E 1.20 across 53 rides (9.4% strike, +10.87 to a £1 stake). The record reads poorly off a 15-30-day break — 3.1% over 32 rides, 4pts below the baseline. The market has consistently overbet the rider on Standard (AW) going: Fair A/E 0.57 across 67 rides (4.5% strike, −13.38 to a £1 stake) — runners there underperform what the price implies. The standout partner of the record: Lucymai (GB) — 5 wins from 17 rides together.

Each tile is the record in that situation vs the 7.1% 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.

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.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 15 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 Jack Duern's strike rate?
Jack Duern has won 8 of 112 rides since 2022, a strike rate of 7.1% (as at 15 October 2026). Figures are computed from our own results archive.
Which yard does Jack Duern ride most for?
Scott Dixon, with 78 rides since 2022 — 70% of the total. That pairing has won 5 (6.4%).
What is Jack Duern's Fair A/E?
0.93, from 112 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 15 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
