The issue is at either extreme there is consensus (Cindy Crawford isn't ugly and Oprah Winfrey isn't beautiful), however, all of the in between is in the eye of the beholder. If I have the thing for redheads and freckles versus someone who does not, then obviously the ratings will differ. If you can find a fellow terbite who has the same preferences as you in an SP, then perhaps it won't be much of a variance.
