Form Ratings are produced by Thoro-Graph™ and are available only on equibase.com

Thoro-Graph™ Form Ratings provide an easy to use evaluation of the current form of horses competing against each other by creating a single rating for each horse. Thoro-Graph™ Form Ratings are based on Thoro-Graph™ Performance Figures, which take into account weight carried, ground loss, effect of wind on the final time, and track speed to provide an overall measure of ability shown by each horse in a race.

Thoro-Graph™ Performance Figures are calculated by using the time of the race, beaten lengths, ground lost or saved, weight carried, and the effect wind may or may not have had on the time of the race. The final figure is manually adjusted with a carefully crafted track variant. Thoro-Graph™ Form Ratings are computer-generated evaluations of horses’ form, based on their most recent Performance Figures earned over the same or similar surfaces.

In using the Thoro-Graph™ Form Ratings, it is useful to look at not only who the highest-rated horse is, but the spread between the contenders, to see how competitive the race is. Sometimes the highest-rated horse is not the favorite, and sometimes a longshot is rated near the top, and worth backing.
