KTB Profile

Imperious Star is a Flemensfirth mare out of a Presenting dam and showed little in three maiden hurdle runs on turf between Feb 2024 and May 2024. She finished fourth of 14 at Huntingdon in May 2024 on good ground in a Class 4 event, which remains her best effort. The mare was beaten on all three starts at trips between 1m5f and 2m4f. She raced at three different courses and never placed.

KTB Speed and Rating

KTB Speed

Best recent Speed 89 the best of the last 2 graded (A or B) runs · Taunton, 6 Feb 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. What this means →

KTB Rating

Best recent KTB Rating 109A the best of the last 3 rated runs · Taunton, 6 Feb 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. 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.
