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...:?

Point taken. New PPF system shelved. We can revisit this in the off-season.

Wise decision,..

If you still decide to reform the PPF system, be aware that a large data set is much more revealing than just an average of 10-12 drivers/cars and their obvious differences.

Just one more thing on GRIP,.. it is so much more than just fat tires against skinny tires. When comes to grip a skinny tire with proper camber setting may be more effecient than a fat tire set at a 90 degree angle. Suspension geometry play a great deal in grip/traction of the car. Another variable when comes to grip/traction is the use of 2 wheel drive VS. 4 wheel drive.

So in short, there is tons of variables to think about when setting PPF value to a given vehicle.
