I see you're talking about bounce back to the SERP, not a pure Analytics bounce rate - that's an important distinction. At any rate, several Google employees have stated that bounce rate is too noisy a signal for them to use - they feel they've got much better ranking signals on hand.

Has anyone seen a -950 OOP recently? I haven't, and none seem to be reported any more.

No - and I've been keeping an eye out for it, because I also noticed that there were no more reports coming into the forums about it. Wonder what took its place, eh? My suspicion is yo-yo rankings (dayparting) because THOSE reports have gone way up.
