Paul Anderson, thanks for the pdf. Your formula employs the
electromagnetic assumption that gravity moves at the speed of light.

 You got this backwards. In GR, changes in gravity propagate at the local symmetry speed, given by SPECIAL Relativity. It "just so happens" [#] that electromagnetic waves travel at this same speed in vacuum. It is merely an historical anomaly that it is called "the speed of light", due to the round-about way Einstein first described relativity in 1905 -- the spacetime symmetry is MUCH more fundamental and important.
