Performance Rates

Performance Rates are an objective measurement of racetrack performance developed by the Jockey Club Information Systems. Performance Rates assign a rate to horses based upon beaten lengths - who beat whom and by how much - with some adjustments made to standardize beaten distances to account for horses that are not pressed or eased in large fields. Time is not a factor in Performance Rates, which are based on every start by every horse in North America. Performance Rates are expressed in lengths around a theoretical mean of zero. The average Performance Rates of the best horses in a given year are generally about 30 lengths better than an average performance of the average horse.
