Cache is built using a square with sides 20 km. User's path has steps of (2000, 2000) metres, with a total of 11 retrievals. Amount of look-ahead (both E and N) is 5km. Cache size is 46.
Threshold for building the cache was 5%.
Point furthest from the centre of cache (29700000, 09700000) is 2835605, 0825684; distance away is: 19.8116 kilometres.
