No, I'm saying the PR values aren't correct for the upgrade path you chose. This problem is still unsolved but I'm going to put some more effort into it as it seems the PR increment for each item is a constant for a car (i.e. Engine is always 0.6x PR increment). Solving x is an easier task if it's constant.

If I can find a way to do it then it will be worth doing it for all cars but it will take some time depending on the number of sample points required. I'm going to get a complete set of data from a car with only a few upgrades and see if I can write a program to work out a set of decimal values that solve all the combinations, rather than trying to solve it mathematically which requires a precise answer.
