Awblain:
I assume that in fact Dr Greaves meant something else in his abstract.
Well, whatever it is you think he meant it is YOU who has taken issue with it. So what I suggest you do is:
a) Clarify in your own mind what you think Dr Greaves meant which is wrong
b) Check you have that bit right
c) Come back to this forum and detail the errors you have identified in his work.
Right now you are obfuscating, shifting position and creating fog.
What is about "1 part in 100,000" that suggest it matters?
Case in point: you can hang onto these tiny gravity anomalies and close your mind to the other effects - more significant - that I suspect were used in the trajectory analysis to get an
effective g. But I don't know for sure. If you have a problem with Dr Greaves' model, it is your point to prove, not mine to disprove.
