Mark,
Get the Texel rating spreadsheets at:

Put the F16 (1) measurements into the Easy Calculator, then change the numbers 1 at a time to the "A" measurements.
It's kinda fun. It'll give you a rough idea where the "A"s gains are coming from.
Hint - change the weight first <img src="http://www.catsailor.com/forums/images/graemlins/ooo.gif" alt="" />
