The RTP (Racers Theoretical Performance) index is a separate set of indexes, calculated from different events, but basically similar. In 2002 both of these indexes were combined when a revised index was created called PAX/RTP. The PAX/RTP Index was developed and is maintained by Rick Ruth of Missouri and reflects study of results from over 200 nationwide Solo events including, the Tire Rack® Solo National Championships, National Tour, Atlanta Region, Chicago Region, California Sports Car Club, Central Florida Region, Great American Solo Series, Hawaii Region, Houston Region, Midwest Divisional Series, Milwaukee Region, New England Region, Northwest Region, Northern New Jersey Region, Oregon Region, Philadelphia Region, San Francisco Region, San Diego Region, South Jersey Region, St. Louis Region, Tri-State Sports Car Council, Texas Region, Washington DC Region, Wisconsin Autocrossers Inc., and many others. Information about the 2012 PAX/RTP is posted and maintained at Chicago Region SCCA PAX Index.

The PAX (Professional Auto-X) Index has been used by SCCA and other clubs for years. It is a handicapping system that attempts to account for performance differences between car classes, allowing the drivers' performances to be compared. A PAX factor is assigned to each class; the faster the class, the higher the factor. The fastest cars have a PAX factor of 1.000; other PAX factors are a percentage based on performance potential relative to the fastest cars. Each driver's actual time around the course is multiplied by their car's PAX factor to calculate their PAX time. This PAX time is also called their indexed time or factored time. PAX times can then be compared across classes.
