I made a reference mark from the stab zero to the firewall, which hit the center of the firewall. The LE is 11/64" closer to that line than the TE, which confirms the horrible downward pitch issues during flight.
Are you comparing the stab incidence to the firewall? More importantly… what is the stab incidence in relation to the wing? When you block the plane up on your bench, put your incidence meter on the wing and shim the plane so that the wing is zero (or what ever angle the wing should be flying at, which I wouldn''t think it would be more than 1 degree plus/minus). Then check the stab incidence to the wing. I can''t imagine you''d want to be more than 1/4 either way. That obviously depends on the airfoil, which I''m not familiar with.
