KTB Profile
Sherkin Island (IRE) is yet to win from 10 starts, though has placed once. Best effort: 3rd of 12 at Down Royal (Jun 2007). Last raced off 91, 18lb below the career-high mark.
A/E compares actual wins with what starting prices implied. "Fair" strips the bookmaker margin from the expectation, so favourites and longshots are judged on the same footing — figures near 1.00 mean the market priced this horse about right.

KTB Rating
Best recent KTB Rating101Cthe best of the last 3 rated runs · Down Royal, 24 Jun 2007Official rating 91at the last run, 21 Jul 2007
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.
