>>On a side note I have started seeing some of the recent supplimentals climb out of supplimental status, but no page rank is given.. in fact the bar is grey, but results are in google?

Though the last supplemental cache refresh for my sites happened around Aug 2005, as GoogleGuy hinted in one of these threads, I'm hoping Google is moving toward a more frequent supplemental cache refresh.

The delay between a cache refresh and pages returning to the index implies Google does those two things separately:

1. Retrieves the content of a url listed in the supplemental database, and either updates the database with new cache, or store the new cache in a secondary database (Since we're still seeing supplementals occassionally reverting back to 2004/2005 even on gfe-eh.google.com, I assume Google isn't letting go of that information. Anyway, maintaining multiple versions of data while working on a project as a safety precaution isn't unheard of).

2. Re-evaluate a page for inclusion into the main index.

For example, Google recently refreshed the cache on one of my pages, which is unique, validated, content-heavy, with unique META description/title, though a bit short on PageRank. I expected the page to be included in the main index during the supplemental cache refresh, but it wasn't. A few days later, I see the page pop up in the main index (both checks were done on gfe-eh.google.com).

In this case, the page remaining in the supplementa index after the cache refresh was probably due to its previous supplemental status, not due to re-evaluation of a freshly cached page.
