This is the fifth in a series of five puzzle caches hidden around the village of Kalithies. The given coordinates are not where you'll find the cache. To find the cache, you'll have to solve the following puzzle:
Yesterday, Giorgos searched on PirateFiles.com and found a copy of the latest episode of his favourite TV show that was exactly one gigabyte in size. As the download began, he was informed that “based on your current download speed, the download will be complete in 5 minutes”. As the download progressed, the time remaining was always 5 minutes, no matter how much of the file Giorgos had already received. As far as I know, Giorgos is still waiting for those 5 eternal minutes to end.
You will find the cache at N36 20.XXX E28 09.YYY where XXX and YYY are the number of seconds (to the nearest second) that have passed since the download began when, respectively, 800,000 kilobytes of the file were downloaded, and the download speed had dropped to 125 kilobytes per second.
The cache is the size of a drink can and contains a log book and plenty of space for tradeable items, though you will need to bring your own pen.
Good luck!
