According to James C. Keith, see appended PDF files, two components of gravitational drag are to be expected on rotating systems, a 1/c5 order drag to be observed preferably on systems of astronomical size, and a 1/c3 order drag preferably observable on millimeter size systems. Observation is limited in either case by experimental resolution of rotational frequency shift. In the early 1970s, Hulse and Taylor [1] determined relative deceleration of a binary neutron star system at 1.5 x 10-12 per second in agreement with theoretically accepted gravitational quadrupole radiation. A relative deceleration of about 2 x 10-11 per second was observed around the same time [2] on a 2.5 mm diameter steel ball at 75 kHz rotational speed. This observation has not yet been accepted by established theoretical science as due to gravitational interaction. The access of experimental results to serious analysis seems to be largely a matter of decision by representatives of theoretical rather than engineeering science.

Preston Guynn:
I very much appreciate your discussion of Keith's electron model starting with equation (38). However, I do not see to what extent the electron discussion is decisive for the effect of retarded gravitational interaction, which already ends with equation (25) and a possible confirmation of Mach's principle.
As for Keith's ability to analyze real physical phenomena, it should be noted that he quantitatively predicted the Coriolis drag of a magnetically suspended steel ball, see reference below and Fig. 2 of the PRL paper cited above (and below).
