Since the Google Page Rank Update from 26.10.2007 I have detect some major changes in the way the Page Rank is distributed over the directories from the Website Submitter. I have run some comparison in my tests.

Number of directories: 3574
Directories type: free, paid, reciprocal, regional


Before Google PR update After Google PR update
PR0 357 1207
PR1 116 328
PR2 376 636
PR3 922 704
PR4 1009 453
PR5 517 172
PR6 204 56
PR7 47 14
PR8 23 4
PR9 2 0
PR10 1 0

You can observe based on the date before the Google update and after a big difference between the way Google PR is distributed over these directories. Infact we can call it a downgrade, the number of directories with PR0 before the Google PR update was 357, after the PR update the number increased to 1207. I have displayed bellow in a graphical mode the distribution of the new Google PR and the PR fluctuations.
