Proper benchmarks of Next would come from using the exact same site setup, the exact same resources served and comparing various sizes and complexities against other tools.
And I say this as a notorious Next.js (actually, *.js) hater.

One of those two things is infinitely more valuable than the other.
Or more simply: compare this to any other website using any other framework. Do you see similar trends ? Are they websites of the same complexity ? If so, why is your initial data set an indictment of Next.js, but not simply of the lack of care most web developers put in nowadays, coupled with "business needs" (read: Google Analytics) ?
Instead it's better to do synthetic tests and then deduce which performance metric is important for my website.
