My main website: still 4/10, but maybe some sub-pages raised (didn't check yet). A secondary website from 0/10 to 3/10 homepage and all sub-pages from 0/10 to 2/10.
Yes, I faced also very quick update on some new websites - 1 month old. But older got PR2, even PR3 Showing that going on right way
Google awarded me with 1x PR5, 4x PR4, 2x PR3, 5x PR2 on my new websites during the first pagerank 2010 update.
