Well, I had to look up the JRXS internal ratio and use my calculator for the calculations, but the formulae are securely locked in my noggin. Then again, I'm math teacher so stuff like that is pretty easy for me to recall and describe, including the algebraic manipulation to discover whichever variable is unknown.
