OK thanks !! CG is by definition located around 25% of MAC. I'll go that route first, and average it for both wings which are not strictly laid one above the other.
Actually nothing could be further from the truth. CG is set by a few things and seldom does the ideal CG position come out at 25% MAC. Look at one of the online CG calculators and all the various numbers that are not related to the MAC of the wing to see what goes into finding the CG location.
