I've answered this question a few times for novices running in our N class that aren't sure what PAX times mean. So, here is an explanation ...
PAX times attempt to compare DRIVERS and nullify the advantage of having a faster car.
Basically, classes with faster cars have a higher PAX value. This value is multiplied to the time you run resulting in your PAX time.
AM cars always have a PAX value of 1.000. The rest of the classes have values based on the previous year's results from national level events and local results from clubs with some of the fastest drivers.
Here is an applied example of how PAX times work.
Compare three drivers in stock classes. Driver A is in a Lotus Exige in SS class, Driver B in a Mustang Cobra in FS and Driver C in a Mini Cooper in HS. All drivers manage a flat 60 second run on the course.
Formula - Raw*Pax Modifier=PAX Time
Driver A - 60*0.857=51.420
Driver B - 60*0.827=49.620
Driver C - 60*0.791=47.460
So, Driver C in the Mini would seem to be a much more capable driver than the others even though they ran the same raw times. (It should be noted that Driver C is not #42.)
