I know that the PageRank update was at the beginning of the month but today when I was browsing one of my own pages which was never assigned a PR during the update.... It showed PR5... i refreshed a couple times, opened a new browser and it kept showing PR5... then maybe an hour later it was back to PR0 ... anyone know what is up with that?
When ever you see such problem, I suggest you confirm the PR via online PR checking tools. I haven't seen any changes in PR for my site.
Confirm the PR by independent means. The toolbar sometimes wobbles a bit in the value it displays. If it sticks at PR 5 for a couple of days, throw a party.
I feel like that always happens to me to, so I check again later using multiple tools to get a consensus.
