OK Bill, what the hell does all that mean!

Maybe a lesson on all this jargon is in order for all us beginners so we can communicate with you.
10.15 Overall Points (Driver’s Championship):
Driver’s Championship event points are based on the percentage of the Index winner’s time and all other Index times. The Index winner gets 10,000 points. To determine other overall points, the winner’s time is divided by the other index times and multiplied by 10,000. The Ladies and Novice Championships are determined in the same way, with the highest placing individual, in each group, receiving 10,000 points for that Championship. Other drivers divide their Index time into the winner’s (Ladies or Novice) time and multiply by 10,000. All drivers are scored. Index points are calculated on a driver’s “corrected” time, including penalties. Points posted to the website may be expressed as xxx.xx (with a decimal).
The Index Championship was mentioned in another thread on this topic.
The PAX Index is a way to calculate the driver's performance, and remove the car from the numbers so that a driver in a Yugo can be compared to a driver in a purpose built race car. A-Modified Class (purpose built race cars) is assigned an index multiplier of 1.000. Every other class is assigned a multiplier that is less than 1.000, based on the finishes of the fastest car(s) in that class at national level events. So the weakness is that the system assumes every car in the class is prepared to the maximum level, like a car winning a national level event.
The local region uses the PAX Indexed results to allow ever driver to compete in one group called the Index Challenge. Take the Indexed time of the fastest driver of each event, divide it by the Indexed time of every other driver, and you come up with percentage. Multiply by 10,000, and that becomes the Index Championship Points for the event.
Andy ran a 52.800 in a SS class car, the multiplier is .858, so his Indexed time was 45.302, the fastest time, and he gets 10,000 points on the Index Championship for the event.
Mike ran a 55.926 in an XP class car, the multiplier is .898, so his Indexed time was 50.221. 45.302 / 50.221 x 10000 = 9021.
Looking at the number over several events should give an idea of improvement, decline, or sameness of the performance of an individual. As long as most of the group of best drivers that usually win the top position are showing up for each event.
Mike disagrees and would rather compare raw times against a small list of known fast drivers in fast cars (like Rick in the Mini Boss Mustang II).
