KTB Rider Profile

Rode around 30 times a season, almost all on the flat, winning on 8% of them — level with the margin-free market read across the lifetime window (Fair A/E 1.00). Rode mostly for John Ryan — 40% of rides in the window.

The read

First rides on a horse have been a poor signal at 4.2% (n=95, Fair A/E 0.61). John Ryan supplied 40% of the rides and edges the rider's average (10% vs 8%, A/E 1.25) — the partnership beats the margin-free market read. The rider also read well off a 0-7-day break (17.6%, n=34) and off a 15-30-day break (12%, n=50). The record read poorly off a 8-14-day break — 4.7% over 43 rides, 3.3pts below the baseline. The market has consistently overbet the rider on Standard (AW) going: Fair A/E 0.71 across 98 rides (6.1% strike, −58.75 to a £1 stake) — runners there underperformed what the price implied.

Each tile is the record in that situation vs the 8% 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.

Quick answers

What is Jack Osborn's strike rate?
Jack Osborn has won 14 of 175 rides since 2008, a strike rate of 8% (as at 28 October 2026). Figures are computed from our own results archive.
Which yard does Jack Osborn ride most for?
John Ryan, with 70 rides since 2008 — 40% of the total. That pairing has won 7 (10%).
What is Jack Osborn's Fair A/E?
1.00, from 174 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. Figures as at 28 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
