Love it :-)
On mobile (on the slightly bumpy subway) I keep mis-clicking because of fat-thumb-syndrome, WAI or bug?

"Everyone should have their own RUM" which would be awesome, but I find that even large websites dont do RUM / action their RUM properly and/or its not accessible outside a too narrow set of roles.

Esp. in Scandinavia iOS is a large blind spot and I fear safari-only UX issues might go untreated forever.

What I would really love is a CrUX Report equivalent for Safari users. Its a really good tool to understand which one of my customers needs help improving their web experiences. CrUX Reports are great to get benchmarks/goals for website owners to aim for.

I ran it already - it only ended up billing 180GB - not too bad. Really useful with the examples and WPT links :)

Awesome, thanks! (Also good idea about a warning comment around data usage as (18TB is what my BQ tells me)).

I'll let you know if I'm able to move anything significantly :)

It was specifically about the "4610 third party domains serving uncompressed content" where I tried to do some spot checking but came up short with that approach.
