top finders location not accurate

Question

Not sure if this should be under Bug reports or not - but asking here knowing it may be moved

I did a recent search for top finders of caches in one country (A) by cachers from another country (B)
I noted that the top two cachers on the resulting list were in fact from country (A) and not (B)
and this is evident from their GC profile as country (A) is given in their profile as home. Also, all their cache hides are in country (A) too.
So how is it that they appear in this search when they are not from country (B) as the filter requires ?
Is it something they have put in their PGC profile that would affect this ?

Answer 1

Project-GC uses heuristics to figure out where people live by looking at your recent logs. If you have just moved, live close to a border or just generally just travel a lot this may fail and assign you to a different area than where you really live. Perhaps this is what's happening here?

In this instance - the cachers in question live in NZ and the majority of their caches have been found in NZ,  they also have a number of hides in NZ
Both have visited the UK, One has found quite a few in the UK so I can see your suggestion working there - but the other has found a few (just over 1% of total finds)
Both come up as being from the UK when it comes to this search
I appreciate the heuristic approach - but that would mean I myself would be constantly changing - This never happened to me however particularly when I spent 3 months in NZ
Anyhow
I would have thought that the logical approach of using the given home location and where the majority of their own cache hides are located as being the country assigned to that cacher in searches like this ?
