+sullivan this is really strange, the graph looks like it has a very clear regression but pinpoint says no.

Indeed, assigned to Ben who is working in pinpoint afaik.

Dave, any idea why this job couldn't find any Histograms?
Also, would it be helpful to automatically select the first or last point in a chart when it couldn't reproduce a difference? That might have made it easier to notice the red "Values" quests.

WontFix-ing this since it's recovered, but also re-running bisect. Will open a bug if it fails again.
