CrUX has FP, FCP, DCL and onLoad (no TTCI/FID just yet). We can cross reference origins with their metrics in Lighthouse from WPT (TTCI) which should show sites with higher TTCI are referencing more third parties.

yeah, I expect the correlation to hold (strongly) as we use more-inclusive metrics (TTI/FID). Was just wondering how so many of those reports seemed to show < 2s ;-)

@tdresser,@roydeepanjan, et. al. did a correlation study to verify that FID maps well to bench TTI. Happy that all of this is *finally* public!1 reply 0 retweets 1 like -

Not public today. Can perhaps make a public version in future.
