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 Speed and Rating
Best recent Speed 123
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 →
