Thanks for the input guys. Seems that most of the opinions come from past experience rather than an aerodynamic standard. I was contemplating making the pivot at mid cord to minimize effects of unintentional dihedral and anhedral while still achieiving the washout angle that moves the tip's LE down and TE up normal to the root.

Maybe it is an exercise in splitting hairs, it is only 3 degrees total after all. I am no expert on this subject.
