John Mackie
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%".
Sends out around 140 runners a season, across both codes, winning with 9% of them — level with the margin-free market read across the lifetime window (Fair A/E 0.99). New recruits from other yards win at 11% first time out (122 runs).
Debutants struggle at 4.5% (n=88, Fair A/E 1.65). New recruits from other stables on their first run are the standout value angle: 10.7% strikes only just above baseline, but Fair A/E 1.64 and +24.38 to a £1 stake over 122 runners — a record the market has persistently underpriced. The market has consistently overbet runners with a claiming rider up: 7.4% strike, Fair A/E 0.81 and −176.62 to a £1 stake over 470 runners — those runners underperform what the price implies. Franny Norton rides 6% of the entries and matches the yard's average almost exactly (10.8%, A/E 1.04) — the partnership beats the margin-free market read. The stable star of the record: Custard The Dragon (GB) — 10 wins from 72 runs for the yard. Seasonally, the yard fires Dec–Feb.
Yard patterns
the angles behind the record · vs 9.1% baselineEach tile is the record in that situation vs the 9.1% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. Headgear figures use the true-first definition (first gear appearance in the captured career); returns are gear back on after a bare run. Claiming riders are runs where the booked rider carried a weight claim. Group / Graded covers pattern and listed races. The same beliefs, tested across every yard and every GB and Irish race since 2005: Racing myths.

Each pick was a KTB figure’s choice before the off — the published KTB Selection, the top-rated horse on KTB Rating, the fastest on KTB Speed — settled against the result the next morning and never worked out again; “did not run” is counted apart. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.
Quick answers
- What is John Mackie's strike rate?
- John Mackie has won 244 of 2,677 runners since 2008, a strike rate of 9.1% (as at 4 November 2026). Figures are computed from our own results archive.
- Which course does John Mackie do best at?
- Beverley by strike rate: 10 wins from 85 runners (11.8%) since 2008. Read from the 15 courses with the most runners 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.
- Who rides most for John Mackie?
- Franny Norton, with 157 runners since 2008 — 6% of the total. That pairing has won 17 (10.8%).
- Is John Mackie in form?
- Too few runners in the last 14 days to read — 8 runners, which is not a sample we will draw a conclusion from.
- What is John Mackie's Fair A/E?
- 0.99, from 2,664 runners 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.
