crbug.com/822865 is an example. The measured frame_times dropped because a big frame time is measured for a period of idleness during an animation. Perhaps we should change how we measure frame_time either to exclude the idle period or measure the idle period as 60fps.
It might not be a big issue when a progression is reported as a regression, but it's an issue in the reverse direction because we may miss some important real regressions.
