@nolanlawson that why we measure runDuration (pure js time) vs. duration which has the RAF to take into account paints and layouts.

I believe @jodarove or @jye-sf were adding the ability to capture those metrics.
Once we have all those we can disambiguate what time does what.

OK, I realize now that I was getting confused by the difference between duration and runDuration. runDuration seems to report the correct, non-rAF-clamped number.

I also discovered useMacroTaskAfterBenchmark: false which avoids an extra macrotask.

It also looks like the console.timeStamp() calls are misplaced, in such a way that it looks like the durations are rAF-clamped. I'll open up a PR to fix that.

Let's open another issue about separating duration and runDuration. This issue may just confuse people.
