KTB Profile

Swiss Mistress is a maiden who was yet to win from eight starts on turf and all-weather. She ran five times over 1m5f – 2m and three times over 1m2f – 1m4f, all without success, and reached a best of fourth of 10 at Nottingham in Oct 2021. The filly, by Mastercraftsman out of an Arosa mare, was aged 4 at her last run in Jul 2022 when she finished seventh of 13 in a Class 6 handicap at Newcastle (AW) in first-time headgear. She last raced off an official rating of 58, 11lb below her highest ever mark.

KTB Speed and Rating

KTB Speed

Best recent Speed 111 the best of the last 3 graded (A or B) runs · Wetherby, 7 Jun 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 66A the best of the last 3 rated runs · Newcastle (AW), 23 Jul 2022 Official rating 58 at the last run, 23 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.
