In "Top-Hiders/Favorite Points Over Time" we can compare owners by their absolute number of favorite points received. That's fine, but if you want to compare the "quality" of the work of two or more owners a better way would be to compare a relative value.
How about a "Relative Favorite Points Over Time (Wilson score)" feature? Favorite points received in relation to hidden caches of this owner and the time it took to collect this much fav-points. That would make owners more comparable.
Owner1: 1000 FP from 100 caches over a period of 10 years.
Owner2: 500 FP from 20 caches over a period of 2 years.
Owner3: 800 FP from 80 caches over a period of 5 years.
Who is the "better" one? Maybe a Wilson-score like statistical analysis can give us an answer.
