I have litterally spent entire days fiddling with the PPF spreadsheet. At one point I got frustrated that it included TOO MUCH data in the equation and then decided to create my own, only to scrap that in the interests of keeping things the same as before.
The PPF formula accounts for:
Vehicle Power, weight, ride height, tire wear rating, tire width, sidewall size, wheel size, power, camber front and rear, suspension stiffness front and rear.
Adjusting ANY of this data affects the PPF slightly. I did my best to include the most accurate information possible. Where info isn't possible (for instance, I'm not forcing everyone to go get an alignment just so I can find out how much camber they are using) I used standard Porsche data.
I can assure you that I have taken this VERY seriously, and I have no interest in manipulating the results for anyone. I am actually considering removing myself from the championship points for the gesture alone.
If anyone would like to dispute their PPF, I will be happy to go over the data.

Jon, could you make sure the PPFs you are posting are those provided by the drivers and not your sole input/interpretation of each car?
Some have PPF lower than last year, others have PPF lower than OEM for same vehicle (how is that happening). I am sure you have sent a spread sheet to each of us, and most likely have received input from them.
Please, in the spirit of a friendly competition make sure that all of us have a fair say about their own competitiveness.
