My 2nd event with the new setup went much better. The higher power level can be a handful. On this run I had too much rear brake bias which made for a pretty wild ride. By the end of the day I was on par with the best I had ever run with the old motor. I took 1st in XP and was 3 seconds off of FTD. Mark made an appearance and got to ride along for on a faster but more tame lap.

Here is the wildest ride of the day:

Congrats on the finish. Only problem with your camera location is you can't see the course in front of you with the sun glare. Sounded great though.

BTW - given any thought to RunNGun?
 
Not as frustrating as Event 6, but it would be nice to get above my average and narrow the margin. My number for my clean run calculated out to a 8556 IC. If they had been generous enough to use my quicker, one cone hit run, (like Mike) it would have been a 8709 IC. Mikes IC was 9021! Andy was first on index, and didn't race in the first five or six events, when Rich and Tom took first. I wonder if Andy pushed the ceiling up a little.

I'm definitely not happy with my lack of improvement and stagnation in my time results, with all the work on new upgrades and driving. Especially with Mike raising the bar even farther.

OK Bill, what the hell does all that mean!:confused: Maybe a lesson on all this jargon is in order for all us beginners so we can communicate with you.
Mike,glad to see it coming around,it will be a beast once figured out.

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).
 
There are 2 major problems with this system:
1. Just a few key drivers can skew the numbers by doing very well on a given day, or vice versa.

2. Some cars are better in a class than others. The Daytona and Imark are not at the top of the XP heap even well prepared. The king in XP is a guy with a stripped Lotus Elise running 300HP and around 1700 lbs on weight. No matter what we do to our cars we will never be able to hang with that car.

A good example is last year Gary did very well at one event on index, yet was like 5 seconds slower than Rick's mini boss. The next event was my best ever. I came within 1 second of Rick yet was much lower than Gary on the index/points numbers.

The punch line at the end of this is that Rick happens to be the one who invented the PAX Index system...

2011 Event 4
Fastest Raw Time 43.154 sec
Rick in CP - 44.878 sec, ICP 9775
Gary in XP - 47.531 sec, ICP 8948
Mike in XP - 49.025 sec., ICP 8675

2011 Event 5
Fastest Raw Time 42.170 sec
Rick in CP - 43.056 sec, ICP 9891
Mike in XP - 43.959 sec., ICP 9393
Gary in XP - 49.002 sec, ICP 8427

The Index multiplier for CP is a little more favorable than XP, and Rick's a better driver with a faster car than any XP car locally. But if I remember, Event 4 was not a good event for Mike, and Event 5 was a very good event for Mike, and the ICP numbers show that. And it looks like Rick also had a better day at Event 5 than Event 4.
