William, I don't know the answer, but if you haven't got
one I would strongly advise getting or borrowing a Smart
Tool so that you can easily and very accurately measure
angles. It does occur to me to wonder whether you are
measuring your up and down angles off the same surface
(i.e. Are you measuring the neutral angle of say the upper
surface, then measuring the up and down angles of the
upper surface, rather than the up angle of the upper
surface and the down angle of the lower surface) Regards,
David Joyce, G-XSDJ
