Interesting that Chrome will stop collecting TTI for its own perf tracking (UMA). https://bugs.chromium.org/p/chromium/issues/detail?id=1039782 …
@anniesullie @slightlylate @addyosmani what is the current thinking for interactivity? FID + Total Blocking Time? Should perf tooling move away from TTI?

Is the cutoff window the main problem or the variance that comes from long tasks crossing the threshold pushing the timings around depending on when the task happened? i.e. do we understand to source of the variability in UMA?
