Solution for object tracking solving inverse perspective ??

Hey all, just tested the new tomato build for object tracking-- object was a monopod with markers and was to be replaced by a gun. I set the solve range to be on one of the recoils since this offered the most perspective shift but blender always solves the projection backwards- tip is toward the camera and back is where the tip should be so cg replacement is impossible. Anyone know of a method that will keep this from happening??:eyebrowlift2:
