KTB Speed and Rating

KTB Speed

Best recent Speed 107 the best of the last 3 graded (A or B) runs · Leopardstown, 11 Jul 2024

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.

KTB Rating

Best recent KTB Rating 95A the best of the last 3 rated runs · Leopardstown, 11 Jul 2024 Official rating 101 at the last run, 1 Sep 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.

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.
