PHY Para taper (Variances) - Art Port

All, 
I mentioned the other day thay I had a couple of rods to mike. This is the
Para 15. Note that I have no way to tell the varnish thickness except as a
SWAG (I think you call it). 
(Some questions below.)

Anybody care to comment? Am I just expecting too much?
