MFJ and Texas Instrument used this type of calculation for antenna Q. The other attachment is what some other people are using with their inverted using the K2AV balun and a Gamma match on bands other than 160M. So I thought why not use the same gamma setup on 160M and not the FCP. So from what you had said best I DO NOT GO THAT ROUTE.
My antenna system morfed into just using my gamma big coil on 160M.
