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 15km. Cache size is 30. (Size is set as a fixed value, derived from original size of 78).
Point furthest from the centre of cache (30700000, 10700000) is 3004805, 0833895; distance away is: 24.6018 kilometres.

Commentary on this starting point: this may be a favourable case as the cache is centred on an area with lots of attractions, and the area outside the cache has fewer attractions.
