+crouleau, FYI.

Looks like these are all false alarms because of Justin's recent "fix". The "lower is better" is incorrect because, for A/V sync, we want things closer to zero. In other words, these negative values became less negative, and that's a good thing. :)

I'll have to cut a crbug to fix the A/V sync metric.
