Hey man, this spreadsheet will be very helpful, but I noticed a mistake. You listed the drop chance for rare gems the same on both Obsidium and Elementium Ore. You have them both at a 1.2% chance to drop a rare gem. The actual drop rate for rare gems on Elementium Ore (according to Wowhead) is 4%.
As a result, this is causing lower profit numbers appearing for prospecting Elementium Ore than what they would be in reality.
It would be great if you could tell me how to edit your spreadsheet so I can get some real numbers. If that's impossible, then a fix would be awesome.
