Well we already have the Wilson score for caches and this works great! For owners we have several lists but it would be an interesting list to see owners sorted by Wilson score!
The Wilson algorithm (for caches) is using percentage (as a quality indicator) and number of favorite points and both indicators are available for owners too so probably an owner Wilson list could be easy to be implemented?
For me I'm always looking for interesting areas for holiday spots. Of course the Wilson lists for caches is a great help but it would also be interesting if an owner is working in such an area with providing highly rated caches.
The cache list will show me the "must see hides" but of course I'm spontaneously searching for other caches in the holiday area too and being on a trip at site, just checking the live map and must decide between two tradi caches with both 20 fps it could be a helpful information if I remember that one of the two owners has a good Wilson score (which I would have checked in preparation of the stay)?
Sometimes there are owners with powertrails or many "standard" caches earning lots of fps and others having just a few caches but with high percentage so the owner by fp list isn't helpful in that case...
