There is no guarantee that any page's PR
will even remain as is, let alone continue to rise; in fact, it could fall.
Owing to the mathematics involved, the grand total of the actual PR
value, range 0 to 1, of all pages included in the PR
calculation matrix must always be 1. Therefore, the simple addition of a single new page cause the actual PR
value of each and every other page to drop, albeit it ever so slightly.
The only way to maintain or increase a page's PR
is to continually being gaining a sufficient number of new inbound links that do not bear "nofollow."
