Hi ... don't think the PR change process is over. Maybe a few days or hours. My main site dropped, from PR4 to PR3, with 2,450 or 3,900+ links, depending what source you check; average 1 new posting of totally original new content, each day; design is always growing, for good and bad, and seo the heck out of the site. A few deep pages, on this site, have PR3 or PR4. Another site went from PR3, last year, to wiped out; not even a zero. Sub page on this site has a PR3, despite google depreciating all links. These might be glitches, for repairing in near future. Alas, that's my story, miserable, but mine. Congrats to those who improved; your hard work paid off. Condolences to those who lost ground. Remember: all google is all temporary. Hope this helps.
Having your pr rise means you are attracting the right type of links. It also gives you a when you see your site has increased it's pr.
