This is an interesting discussion. I've always given FM the benefit of the doubt on PR scores, meaning that I assume they are based on a consistent formula applied to the underlying performance specs.

The apparent inconsistencies I've assumed are due to how performance specs are reported to us as a single number, while in all likelihood in the underlying physics engine they are a function. So we get a single grip number, but PR is calculated from a grip per speed function that may also have other variables. We get a single brake number, but what underlies it is a decelleration vs speed function, etc. The inconsistencies arise because the different functions create different performance curves, but we just see one point on that curve. Depending on what point we see (our "snapshot" of the function), cars with quite different functions may be reported as similar if the curves are close at that point. Or, on the otherhand, the differences could be overstated if the snapshot is from the point of maximum divergence.

On the P1 GTR vs C-X75 comparison, it's apparent that the P1 GTR has better grip at high speed, but we don't see that from where the snapshot is taken. [That said, the very high F1 car grip levels are likely reported at high speed. Perhaps where the snapshot is taken is not consistent]. In any event, the performance spec "snapshot" and PR calculation flatters the Jaguar, making it seem closer to the P1 GTR than it actually is. I wonder how much lower the Jaguar PR would be if the top speed was the same as the McLaren.
