"Slaying giants" is of course heavily dependent upon the hardware and drivers that show up to your local autox events.
PAX is Professional Autocross, and is also sometimes referred to as RTP or Racers Theoretical Performance. It is an index that allows drivers in completely different classes to directly compare their times, with a focus on the drivers abilities more than the cars performance potential. To be totally accurate this also assumes the cars are equally well prepared within their respective class rules. Yet even for people with less than ideal cars for their class it still provides a great method of benchmarking how you and your car are performing, especially against more skilled (and consistent) drivers in better prepared cars. Many clubs will also offer an FTDI (Fastest Time of the Day Indexed) award/trophy that is coveted especially amongst drivers not running a car in one of the fastest classes. Heck, I almost considered having my solitary FTDI T-Shirt framed...Of course that's mostly because my wife keeps trying to throw 'that old rag' out.
This concept tends to trip up people not already familiar with it, so it's often easiest to explain with an example. Assume you're driving a nationally competitive car in a class with a .832 index factor and I'm doing the same in a class that has a .910 index factor, your fastest time was 72.115 seconds and my fastest was 65.935 seconds. Now your indexed time would be (.832)(72.115)=60.000 seconds and my indexed time would be (.910)(65.935)=60.001 seconds. So even though my raw time was over 6 seconds faster than yours, thanks to my beastly car, you were theoretically the faster driver.
Anyways, congrats on the FTD. I thought every non-alien driver feels rusty their first event or five of the season.
And yes...this thread needs more pictures!
