Calculating stuff is fun?  ??? Hah, just kidding...though I, personally, find it boring. So I took out some of the work out of each calculation. Makes things easier for me.<br/><br/>MOP, look at my sheet, and tell me if it makes sense to you. The cheat sheet I make you will end up looking like that, and I want to know if it's confusing or anything, so I can make improvements for you.
