+dtu is this kind of bisect (on benchmark duration) already supported by pinpoint?

Not sure why all builds return with: "ReadValueError: The test didn't produce chartjson-output.json."

I think it should work. Filed https://github.com/catapult-project/catapult/issues/4141 for the failure.

+nednguyen I noticed this spike on benchmark duration on several benchmarks, are you aware of anything that could have caused it?
