Ok so the equation is hidden, ok I get that there is a reason but I don't need to know why it is hidden. A major reason why this thread was opened was after a lot of research I could not find the equation and maybe some are in the same boat as I am in. Guess I will need to ask around to see who has the equation.
The equations were hidden not so long ago to try and make production less of a numbers/spreadsheet game. However outspoken criticism from many about the pointlessness of doing so may of cause some rethink on that and it may be that the equations will be returned with a sync. However I may of misinterpreted some of those discussions.
