37 PR10 sites drop to PR9

October 8th, 2004

This Oct 6th PR update saw 37 out of 152 PR10 pages drop to PR9’s. The following are the PR10s that moved to PR9s for each company.
Adobe 4/51 pages, Apple 7/27 pages, Google 7/35 pages, MicroSoft 5/6 pages, w3.org 2/4 and nsf.org 1/2 pages. Beside these pages there were 11/28 sites that had their only PR10 page drop to a PR9.
One theory why this has happened is that real PageRank has a maximum value of the number of pages in Google’s index. As the index gets bigger the real PageRank number increases.
When the real PageRank numbers increase, the range of each of the toolbar scale units moves up. When this happens the lower range of real PageRank in each toolbar unit (except the toolbar PR1 as it covers the very bottom of the real PageRank numbers) is then covered by the toolbar PR value below. Some hold that this is why 37 PR10’s slipped to PR9’s in this toolbar update.
