A lot people are goofy with math. I am no expert and could not handle proofs and differential calculus. Ratios I get and that's why I wrote out a procedure. Keep track of it and you can see a trend.

Also if you have a smart phone, there is a bunch of free MPG calculators you can use. I used to use one. It was cool as it kept a max and min.
