The stand out for me is how much the F82 benefitted using MP4S. That's a crazy decrease in lap time by just swapping MPSS with MP4S.
This says to me that tyre advancement is a significant factor in the G8x lap time improvement. Which makes total sense to me as the sum of the improvements were not adding up to a significantly faster platform.

It’s interesting you’d say that, because my experience of the first gen PSC2 tells me they are worth less than a second per minute lap over the PSS on a single flying lap. Similar to what we see here between the PS4S and the latest gen PSC2. The main benefit of the PSC2 is that they tolerate heat better and therefore do not fall off as fast as the PSS/PS4S after multiple laps. And even the PSC2 (at least the gen-1 BMW star spec) aren’t that good either, they start overheating and chunking away quite fast when really pushed.
And I think you might be misreading what car is tested with the PS4S here, the 1:33.98 time is the G82C with its stock PS4S, not the F82C...
