KTB Speed and Rating

KTB Speed

Best recent Speed — no A or B graded figure in the last 3 runs; the figures below carry grade C

How fast the horse ran, as points against the day-corrected standard time for its course and distance: 100 is the median GB Class 4 handicap winner on that code; one point is 0.1% of the standard time. A, B or C is how much the day's card could tell us, not how good the run was. What this means →

Jumps 1 figure · too few for a breakdown

Of 4 runs looked at, 3 have no figure: did not complete (3).

KTB Rating

Best recent KTB Rating 92C the best of the last 1 rated run · Killarney, 22 Aug 2024

What the horse achieved in each race, in pounds on the official-rating scale, from the weight carried, the lengths beaten and the race's own level solved across the archive — never the market, never the official rating as a starting point. The headline is the best of the horse's last three rated runs on that code. A, B or C on a run is how much known form was in that race. What this means →

Jumps 1 figure · too few for a breakdown

Of 4 runs looked at, 3 have no figure: did not complete (or a non-runner row) (3).

Both figures are KTB's own, computed from the archive; no vendor rating enters either. Every run's figure is on its form line below with its grade. Grades measure how much the archive could see, never the merit of the run.
