How you rank, and what your PR is are two different things and are not always related to each other. You can rank #1 for a term with a PR0, or you can rank 100th for a term and have a PR10.

The point of your msg seemed to be that this persons website had 'optimization' and yet it had a PR4/Good results. Im just saying that those things are unrelated.
