just in case anyone has been sitting, waiting for it to uncover it's self, i did the math for how long you'll have to wait.
777601 (seconds) / 100 (total %) = 7776.01 (seconds per %)
7776.01 (s/p) / 60 (seconds in a minute) = 129.0016 (minutes per %)
129.0016 (m/p) / 60 (minutes in an hour ) = 2.1600026 (hours per %)
so, if it is set to be uncovered even between each %, you will be waiting approximately 2 hours and 16 minutes. just thought you people hitting refresh every 5 minutes might like to know :D
