You're welcome Horace. Your calculation of the torque effect seemed sound to me, I can't remember how I had done it at the time.
There still seems to be something way wrong from a Newtonian viewpoint. The gravitational force is linear between the sun and earth. There is no angular momentum component to the sun's gravitational field, at least from a Newtonian viewpoint. And yet, a change in angular momentum of the earth results when precession occurs, and further it depends on the initial earth angular momentum, the angular velocity of the bulge. No rotation, no precession. And yet the gravitons, if such exist, leaving the sun, have no way of "knowing" in advance if the earth is rotating or not. The Newtonian gravitational field of the sun doesn't change it's effect on earth depending on whether earth rotates or not. Conversely, from a Newtonian standpoint, the gravitational field of the earth acting upon the sun differs not depending on whether the earth rotates or not, or sun rotates or not. Newton falls apart utterly. This is apparently not an action-equal-reaction situation. Angular momentum appears not to be conserved instantaneously from a Newtonian viewpoint when the earth rotates and thus precesses. So much for assuming a mass exists at its center of mass too, for calculation purposes. It seems to me gravimagnetics or some other invention is essential to restore conservation of angular momentum, at least on an instantaneous basis.
