I would say it is all in the aquaplas. Rob sent me his data files and I will normalize them. I'm also evidently going to have to go through a 2435 and ensure it is "good" along with new ferrofluid, measure it, aquaplas it, and measure it again. I'll also compare it against a stock 435Be. I guess I'll use an H9800 or H4338 for the measurements. I really wish I had more time for this kind of stuff..........
