There is evidence (though I've had no reason to follow it up) that
there are at least two PR servers (which you'd expect with the amount
of queries they must get a day).

If there are multiple servers at times some will be more up to date
than others and so different people will see different PR results.
Also Google is known to test things out like algo changes on some
servers earlier than others, so why not the same with the PR toolbar
readings.

Some here have experienced this with what has been jokingly referred
to as a predictive toolbar. They see different PRs than the rest of
us, usually noticed when a big change occurs.
