Not surprising at all that SourceHut came out on top, but the gap between Github and Gitlab is interesting.

This is probably too much to ask -- it would be great if in the future this page would be expanded by location where the lighthouse was run on. I would be curious to see if there's any variation found across countries.

In my experience running lighthouse locally vs Google's PageSpeed Insights gave non-trivially different results, never did figure out if that's purely because of different location this is being run from, or if I just failed to exactly replicate the configuration of the run PageSpeed Insights uses.
