CAT Scale Readings
I have seen much information on using readings from Cat scales that use 3 different reports. (First with TT hooked up with WDH on, then same with WDH off, then only TV) But I recently read a post where they only used the first and third reports. There was a calculator posted where you can enter these numbers and get all the pertinent info. I have looked until my eyes are crossed trying to find that calculator, and am wondering if anybody knows where to find it.
