KTB Rider Profile

Rode around 50 times a season, almost all on the flat, winning on 5% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.88). Riding last-time-out winners the record reads 16% (38 rides).

KTB at a glance Fired Mar–Apr Willie Musson: 8.5% from 189 LTO winners: 15.8%
The read

The record is strongest at Kempton (AW) (11.8%, n=68), clear of the rider's 5.2% baseline. Rides on last-time-out winners have been a positive signal at 15.8% (n=38, Fair A/E 1.10), but first rides on a horse have been a poor signal at 1.7% (n=288, Fair A/E 0.43). The market has consistently overbet rides in big fields of 14 or more: 1.9% strike, Fair A/E 0.52 and −80.75 to a £1 stake over 104 rides — those runners underperformed what the price implied. Willie Musson supplied 33% of the rides and edges the rider's average (8.5% vs 5.2%, A/E 1.02) — the market has that partnership priced right. The rider also read well over 1m5f – 2m (13.2%, n=53). The record read poorly at trips under 6f — 0% over 67 rides, 5.2pts below the baseline. The market has consistently overbet the rider over 6f – 7f: Fair A/E 0.32 across 215 rides (1.4% strike, −186.90 to a £1 stake) — runners there underperformed what the price implied. One Group or Graded win sits in the archive record — the biggest prize the rider has landed: the E B F Joan Westbrook Pinnacle Stakes at Haydock (May 2007, £19,873). Seasonally, the rider fired Mar–Apr.

Each tile is the record in that situation vs the 5.2% 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.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 6 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 Jamie Mackay's strike rate?
Jamie Mackay has won 30 of 579 rides since 2008, a strike rate of 5.2% (as at 6 November 2026). Figures are computed from our own results archive.
Which course does Jamie Mackay do best at?
Kempton (AW) by strike rate: 8 wins from 68 rides (11.8%) 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 Jamie Mackay ride most for?
Willie Musson, with 189 rides since 2008 — 33% of the total. That pairing has won 16 (8.5%).
What is Jamie Mackay's Fair A/E?
0.88, from 575 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 6 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
