KTB Rating

Best recent KTB Rating 49A the best of the last 3 rated runs · Newbury, 11 Jun 2015 Official rating 55 at the last run, 20 Jun 2015

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 — its best recent day. The KTB Rating on a racecard is a different reading of the same figures: the level the horse has been running to, an average of up to its last six runs with the latest counting most, so the two can differ. 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.

Run style is derived from in-running commentary, which our data provider does not supply for this horse's races.
