At NWOR, we use the PAX/RTP (Racers Theoretical Performance) Index to determine the winners in our Novice and PAX classes. This Index was developed by Rick Ruth and reflects study of results from over 200 nationwide Solo events including, the Tire Rack® Solo National Championships, National Tour, and many Divisional and Regional events across the country. Basically, the index is a multiplier, designed to compensate for the differences in car performance, thereby shifting the emphasis to driver ability. In plain English, (for example), it allows someone driving a Geo Metro in HS to compete fairly with someone driving a Dodge Viper in SS.
