Issue descriptionso far isolated to one test on nexus5x bot. ref graph hasn't updated in a long time, so not sure if this is noise.

Ref graph last updated at revision 424054. https://chromeperf.appspot.com/report?sid=984fd6d176419670e17174d297e7366523ac4e98c9488418bb9f38fc6b707ac9 Caleb, seems like the build may have been broken around that time - can I bump the ref graph to a new revision to see if it will start working?

The ref build has been broken because the ref build is broken: before sandersd@' fix to prevent us from timing out in the middle of a seek, the bots would time out in the middle of seeks and the tests would break. Not sure if there's anything we can do... I thought we were just waiting until the reference builds magically start working again once the fix gets streamed up to them as well. Bisect should still work.

The reference build is at M58. Not sure when sandersd@'s change went in.

Another bisect with wider range - if this one doesn't find I will assume this one is noise (no ref graph to argue either way, only data point we have is failing bisects).

Closing per plan in in comment #11.

Makes sense. The problem here is the ridiculously high standard deviations. If we could find a way to make these tests less flaky, it would make these bisects find relevant information. +johnchen@ for reference.
