Yes, and the velocities stated are in earth-centered inertial
coordinates, just like I said they were. Will you at least
concede that much?

Nobody is being "dogmatic" here, so what's your point in
attacking that strawman? When the decrease in gravitational
acceleration with distance is taken into account, the distances
between the faster object and the slower object are greater than
they would be when assuming a constant acceleration. I did a
simulation for the the midcourse correction given the velocity
and altitude in the mission report. The difference after 48
hours is more than 900 miles, so the estimate  of 400 miles
arrived at by assuming a constant acceleration was too
conservative. (The simulation I did considered only radial
velocity, whichs isn't too bad an assumption for the midcourse
correction because the velocity was mostly radial with respect
to the Earth at that time.)

Possbibly, maybe, but what basis do you have to claim that it is
probable? There were firings of RCS thrusters throughout the
mission before and after the sighting of this object, many of
which would be as likely as any other firing to dislodge
something from the lunar lander. Designing the spacecraft so
that there would be sufficiently forceful impingement of RCS
exhaust upon the lunar lander to dislodge something would seem
to be a very poor and potentially lethal decision.
