I am going for 85 mining at the moment (100k until 80 atm) and to make it not so boring I am multi-tasking and programming an Application for use when I get 85.
Its called runeTimer its a web-based application that uses the world's population and a formula to figure out how long until the ore is back after you mine it.
Its currently still in development, The basics are built but I have absolutely no javascript yet so it requires page reloads (It won't when I am done),. And I have no security yet.
If any one here has 85 mining contact me on rs at TexasMd91 or PM me on the forums here and you can help me gather a few statistics for the rune formula (currently only have the adamant formula).
