SEOTheory..Nope...again...my thought is that it's not bounce rate....its bounce rate when they return to the google serp and then they click on another site in the SERP's and then they dont come back to your site. If I were google, this is a major signal that I'd use to measure quality of the pages in the search results...if you don't think that's being measured and used, that's fine...I believe it is....and I believe its one of the biggest factors in Panda...and my plans for clients who were effected is to work on having searches think that my clients site is the final destination for what the searcher is seeking... I feel confident that by at least going on this premise, that the advice that I'm giving to clients is in line with what Google would like to see for results in the SERPS.

The day after Panda was released, there was an interview with Amit Singhal (a google engineer) called "Google’s Singhal On Why Google Had Spam Issues"

to quote that article:

"Singhal did say that the company added numerous “signals,” or factors it would incorporate into its algorithm for ranking sites. Among those signals are “how users interact with” a site. Google has said previously that, among other things, it often measures whether users click the “back” button quickly after visiting a search result, which might indicate a lack of satisfaction with the site."

So you can ignor those words if you'd like....that's your choice.

Yes you're right, it's not bounce rate. I never said it was. Bounce is a bulk metric....What I am talking about is a segmented notion of bounce rate. There are multiple ways to bounce off site, they can go anywhere....but the problem is...if they came in via a google search, and then returned to that search, then I feel that that is the problem...and those metrics you can not measure. Your right, it's NOT Bouncerate...it's the part of bounce rate where they go back to the google search and click on someone else....that can not be measured via bounce rate.
