 How are you assuring that the back of your jig is lining up with the center
of the cord line? Did you have you airilons and flaps on?

  I measured outboard from the BL25.5 inboard edge of the wing and placed
masking tape on each wing at 1 foot intervals.  I knew it was important that I
was measuring both wings at the exact same points. I leveled the fuselage and
wings.  I ended up only checking every 3 feet because it was a pain to adjust
the jig.  It still gave me 6 measurements.
