If you only have one PR (or one remaining PR) on your report, and it falls off due to age, PFD, etc., you are re-assigned into a new score bucket with others who have no PR's. Lots of time your scores take an initial hit, because your new credit peers have better reports overall, but as you go along, cleaning up, maintaining good history, maybe adding some more credit, your scores pass where you were and keep going.
