KTB Profile

Diamond Girl ran four times between May 2022 and Jul 2022 without winning or placing. She finished 11 of 11 at Wolverhampton in Jul 2022 when last raced off OR 47 in a Class 6 handicap. The filly, by Profitable out of a Holy Roman Emperor mare, raced on turf at Chepstow and Windsor as well as twice on the all-weather at Wolverhampton. All four starts came between 6f and 1m1f on good to firm, good or standard going.

KTB Speed and Rating

KTB Speed

Best recent Speed 81 the best of the last 2 graded (A or B) runs · Windsor, 23 May 2022

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 43C the best of the last 3 rated runs · Chepstow, 20 Jun 2022 Official rating 47 at the last run, 5 Jul 2022

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.
