I have written a checker that tests for n finds between degree x and degree y. Can be limited to within a country or a region/state.
Allows for caches in the style of "New Zealand in 500 Minutes Challenge": find 500 caches representing different minutes across the length of New Zealand, which is 954 minutes long. There will also be a 1000 Minutes of Norway challenge soon.
Feel free to use this anywhere you need it.
