Understanding PAX Factors
The PAX factors are derived from comparisons of the best drivers in the different open SCCA classes in a selected series of events. Thus a PAX factor is a sort of handicap with a PAX of 1.000 being for the fastest class of cars (A-Modified). Let's look at an example.
RAW TIMES FOR SAME DRIVER IN CARS IN 3 CLASSES
To understand PAX factors consider what would happen if one of the best drivers in the country practiced in three different cars which were prepared to the limit of the rules for their class and then competed in each car on the same course. That driver would achieve the raw times in an AM, SS, and HS car shown at the right.
 
PAX FACTOR CALCULATION FOR CARS IN 3 CLASSES
Therefore the fastest car is the AM car and the slowest is the HS car. If we were to divide the raw time for the fastest car (AM) by the raw time for each car we would get the PAX Factor relative to the fastest car as shown to the right.
 
PAX TIME CALCULATION FOR CARS IN 3 CLASSES
If we now MULTIPLE the raw time for each car by the PAX Factor we will get the PAX Time for each car as shown to the right.
 
PAX TIMES FOR 3 DRIVERS IN 3 CARS
So, the PAX Time for each car is the same, which is what we would expect if they were driven by the same driver with ample practice in each car. But, what would happen if each car was now driven by a different driver? The process is the same...MULTIPLE the Raw Time received by each entrant by the PAX Factor for the car's class. Suppose the results were as shown to the right.
 
As you can see in this example the car actually winning the class would be the HS car because the driver turned in Raw Time which gave a PAX Time better than the others. The driver of the SS and AM cars did not extract the same potential as predicted by the PAX Factors which says they should have received faster Raw Times.

Since it is not possible to get the same driver trained in the best prepared cars in every class, PAX Factors are derived from buttstuffyzing the results of top drivers in the best prepared cars in several selected events across the country to try and determine the predicted performance of fully prepared cars in a given class.

OK, you want a freaking explanation for every little f-ing thing, FINE! [COLOR="Red"]Here you go big shot![/COLOR][COLOR="Blue"]<---guess that's me =)[/COLOR]

That explain it well enough yet?

I did manage a 44.830 (FTD was a 36.3 ish? in a Carerra 2.7 RS and [COLOR="Red"]most of the Boxter's/Caymen's were in the 46's [/COLOR]so I was mid-pack. Slow man out was a 47.9 in a 914).

your posted results differed from those on the official results page.
when you appointed yourself as the caretaker of the of the FTBCF top 25 you also placed yourself somewhat in the spotlight wrt records keeping and such. when you put up differing numbers(for whatever reason), it makes people curious.

Or is it you don't believe I won the bracket race? It's OK, I can provide that too:

Is everyone drinking this?

Both cars are also in their online "system". So while normally showing up in a different car would cause a little delay, in this instance there was none.

I still don't understand why everybody jumped me for my "guesstimation" when the Official Results weren't even out yet.

Hey all!  Just got back from my first auto cross!  I had a blast!  Wish I had done better, but that will come in time.

How many of you bashed the snot out of carpimp over his paint job? Seriously take a gander at the "tone" of this site overall. I'm not the first person to point that out this year either...

John and I both got 8 runs. The RX-7 ended up with a 44.795 best time (John got 43.887 in the GTO). [COLOR="Red"]We were smack in the middle of the pack[/COLOR][/B]
