Yes, you do, which is pretty much what we do already. Okay, The approach 
I tried worked better than I expected the first time on my (only) model, 
so I pitched it out there to see where it landed. I suspect we'll never 
have anything particularly accurate, and will be guestimating, 
averaging, and fudging with any system we try. The direct proportion 
measurement changes as well, depending on where it's taken, be it over 
the pin, or further forward, so we don't have anything particularly 
absolute as a comparison baseline.
