OK I have seen my PR7 home drop a point to 6, i have done future PR checks an see variation 6 or 7 on 50% of datacenters. New subdomains have gained some PR not as large as would have been under previous algo's. Newer domaindsall got some PR. I havent acquired many / any new incoming links in that last 6 months so I guess I might be spreading things a little thin. It will be very intereting to see how it pans out.
