I've been working on the PPF formula today that we have been using for the past few seasons. It's a very complex formula that is designed to equalize the performance of all the different cars, that we got from the Maverick PCA region. The problem is, that this equation is built into a Microsoft excell spreadsheet that hasn't been updated since 2006, and that region doesn't even use this anymore since they scrapped it for a simmilar system a few years ago. We have been entering information in for newer cars, but it is unreliable because I don't know what the actual formula is. If there is anyone here that knows excell spreadsheets really really well, by all means, give me a shout and help me out.

I would like to propose we use a different system that works as follows:

Grip + Weight + Power = Performance

In a nutshell, vehicle grip, weight and power all combine together to give you the performance of a vehicle. So for the purpose of car equaliztion:

Your cars Grip + Your cars Weight + Your cars Power = AVG of the 3

DIVIDED BY

AVG Grip + AVG Weight + AVG Power = AVG of the 3



I'm using the following information in the calculation:

Front Tire Size, Rear Tire Size, Tire hardness (UTQG), Weight, Power


What does everyone think? Feedback?

So your system allote the same weight for each component : 1/3 for weight of car, 1/3 for grip of the tires, and 1/3 for power. Which in reality, for autocross, handling is the most performance enhaning mechanism. This mostly comes from suspension and tires, and a great deal of the weight of the car plays in this equation. Although much less can be attributed to the horsepower of a car when comes to autocrossing. ( A good example is Chuck and Nick's car light weight and low hp). But to dedicate the sme ratio for HP, Grip, and weight, is a mistake in my opinion.

This system disproportionatly advantage the cars that sits on the extrem range of each component.

May I ask why do we have to re-invent the wheel,....especially after the season has already started...:?
