Your message makes it sound like you are getting inbound links from a PR7 site (or, possibly ten of them).
I think a little clarification might help...
Note that you may get some increase through convoluted means (gaining more inbound links because you are now a 'hub' site, getting a thank you link back etc.). But this is not what you were asking.
