It seems to me like the process begins with a page-by-page assessment. A site-wide score is then applied, based on how many good quality pages versus low quality the algorithm scores. So it's not a black and white situation, not just page-specific or only sitewide.

Yep, and Google admitted this much. Now the question is, what it takes to fix it and how long after Google sees it are ranking restored?
