Attractiveness is subjective so you can't really find a true middle ground. For example maybe there are people who like above 71mm ipd for some reason, so there are a lot of people who will find the ideal ipd unattractive or maybe even repulsive. So I am saying that the table of contents to find the average will have three columns ie ipd, frequency of ipd when liked (which itself might be a range) and average intensity of attraction (which will be derived from another set). Instead of this when we use image superposition the resultant image ends up somewhere near the face of the evolutionary apex ancestor. Now when we say evolutionary apex the problem is that we don't know if it was his or her attractiveness or something else that made him or her the apex. And you won't find the average person of the world website because that might be too controversial since either someone will claim that the resultant is either the apex or most attractive and the resultant's apparent race is the superior.
