RE: Showtime
take a level, put it on the front of the fuse, keep sticking stuff under the tail until the firewall is level. then zero your incedence meter on something level too, then measure.. or you can just do it the way you have it by Zeroing the incedence meter on something level and then measuring the flat area on the plane like you did with the meter and just do the math for the difference on your wings and stab.. but the firewall method works great..
