I found this on Digital point from User Sweetfunny and have tested it and this does produce a different result to that of the main Toolbar.
For those who want to see the new values in their Toolbar:
On Windows XP

Save and close, you will now be able to browse with the new PR values.
As far as I can tell this is not the final PR output but one of many data centers that are updating. I should give you an indication of where things are heading.
