Apr 11, 2017 at 5:01 comment added NickD ... a factor of $\dot{\phi}$ missing... There's some kind of irony here :-)
Apr 11, 2017 at 3:18 comment added NickD BTW, I think there is a factor of $\dot{\phi}$ after the first equals sign in the last equation for $\Delta\phi$ in the "General Result" section. But everything is fine after the second equals sign.

Jul 9, 2016 at 15:36 comment added Diracology @WetSavannaAnimalakaRodVance IMHO the beauty of the general result is that it does not specify the nature of the perturbation $F_p$. If one uses $F_p=\beta/r^ 3$ one gets the 43 arcsec per century of GTR.
Jul 9, 2016 at 15:17 comment added Selene Routley +1, I really learnt something from the second section - how elegant. Like the OP I probably wouldn't know where to begin, and imagined it would be a detailed tallying up of forces from planets separately over long time periods. That fast-compared-with-precession insight to replace the planets with rings is wonderful.
