KTB Rating

Best recent KTB Rating 93C the best of the last 1 rated run · Hereford, 6 Feb 2005 Official rating 102 at the last run, 29 Mar 2005

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: no runner of known ability in the race — the level cannot be solved (2) · did not complete (or a non-runner row) (1).

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.
