Hm, not so sure.
There seems to be regressions in a number of non H264-related tests. Such as a similar huge spike in BWE for 
ChromiumWebRTC/chromium-webrtc-rel-7/browser_tests / bwe_stats_VP8 / available_send_bw

There also a curiously large range for this data point:
Chromium Commit Position range: 429861 - 430548 

For most other data point there seems to be anywhere from a single one to 30 or so revisions. Not almost 700...

For now, assigning back for further triaging.

Ping? I'm a little worried about this one. I think it made M56 cut as well?
Looks bwe-related to me. terelius@, can you have a look?

Is this caused by https://codereview.webrtc.org/2430133005 ?

What happened to this one? 

Removing R-V-G label (was set upon bug filing because the bot was incorrectly configured as internal)

I believe this is fixed now
