What's a stddev bisect?

By default, the bisect dialog on the dashboard bisects the "mean" (probably not quite correct with the new classification algorithm). But it has a return code option, and also a std_dev option. The latter used to bisect on increased noise. See the blocked bug for example use case.

It doesn't make sense to have the distinction with the new classification algorithm.

It sounds like there is another bug with the bisect in https://bugs.chromium.org/p/chromium/issues/detail?id=596817#c7 ?

I'm okay with fixing that and removing the UI for std_dev bisect in the dialog, as long as the use case is still met. It might be better to file a blocking bug for 596817 that is specifically about the bisect issues though.

This is an old-ish auto-bisect bugs. This might be fixed with Pinpoint, or it's not going to get fixed. If you disagree with me, please reopen the bug and mark it "Untriaged".
