Not sure what you're saying; Jerry isn't trying to confuse us, he's looking for constructive criticism. Other than Occam's razor, nobody has poked any real holes--a specific counter example or calculation error--in his basic idea yet.
I’d like someone intimately familiar with navigation of interplanetary probes to comment on the subject—exactly how would a variable G affect the course, can we detect the effect, and if we can why have we not (course corrections?).
One report I’ve read on the Pathfinder landing may be relevant. I was unable to find any anomaly that would seem to result from an underestimate of Mars’ density. However, I’d like to read reference #2 from that paper, as it discusses changes to the landing program accounting for cumulative navigation error. My local research resources are not extensive enough for old AIAA conference papers, unfortunately.
