KTB Rider Profile

Rides around 210 times a season, almost all over hurdles and fences, winning on 13% of them — level with the margin-free market read across five seasons (Fair A/E 0.97). Riding last-time-out winners the record reads 19% (146 rides).

The read

Rides on last-time-out winners have been a positive signal at 19.2% (n=146, Fair A/E 0.90), but in Group and Graded company the record reads poorly at 4.9% (n=41, Fair A/E 0.48). Kim Bailey supplies 38% of the rides and matches the rider's average almost exactly (13.8%, A/E 0.94). The rider also reads well beyond 3m (23%, n=74) and in Class 3 (19.6%, n=163). The record reads poorly in Class 1 — 6% over 67 rides, 6.6pts below the baseline. 39 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Fleur De Lys Chase at Lingfield (Jan 2022, £79,725). The standout partner of the record: First Flow (IRE) — 12 wins from 26 rides together. Seasonally, the rider fires Oct–Nov.

Each tile is the record in that situation vs the 12.6% 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.

This filter uses derived form angles computed for 8.1% of the archive so far (as at 8 Nov 2026); the sample will grow as sequencing completes.
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.

Runs, wins and places only: a strike rate or a return on a handful of runs is noise, so none is quoted per horse — each horse's full record is on its own page.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 8 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.

the forward record · since 5 Oct 2026

KTB’s figures on this rider’s mounts since 6 Oct 2026: the KTB Selection in 3 runs (won 0) · top-rated on KTB Rating in 4 runs (won 0) · fastest on KTB Speed in 2 runs (won 1) · to 3 Nov 2026.

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 David Bass's strike rate?
David Bass has won 134 of 1,065 rides since 2022, a strike rate of 12.6% (as at 8 November 2026). Figures are computed from our own results archive.
Which course does David Bass do best at?
Ffos Las by strike rate: 7 wins from 37 rides (18.9%) since 2022. 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 David Bass ride most for?
Kim Bailey, with 407 rides since 2022 — 38% of the total. That pairing has won 56 (13.8%).
Is David Bass in form?
Too few rides in the last 14 days to read — 14 rides, which is not a sample we will draw a conclusion from.
What is David Bass's Fair A/E?
0.97, from 1,064 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 8 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
