KTB Speed and Rating

KTB Speed

Best recent Speed 110 the best of the last 3 graded (A or B) runs · Leopardstown, 10 May 2026

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 →

KTB Rating

Best recent KTB Rating 97A the best of the last 3 rated runs · Leopardstown, 10 May 2026 Official rating 110 at the last run, 28 Jun 2026

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 →

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.

Splits include every sample, however small — muted rows are under 3 runs. A one-from-one record is a fact, not a trend: read the Runs column before the strike rate.
