Hi,
The archive is producing reports based on a subset of pages they handle.
It's based on automated analyses of pages which record all manner of details, as found on real sites. This includes all manner of measurements about fonts, css, markup, page weight and more. I haven't read it all but found some of the information about fonts interesting. (Some other parts did not impress me as much.)
I noticed that they don't have anything substantive on validation though.
Some sections are not yet done. Of those, I'm interested to see what they say about Privacy.
Here's the contents page: https://almanac.httparchive.org/en/2022 ... f-contents
If you want the front page of the report here it is: https://almanac.httparchive.org/en/2022/
