Hey Candice - Sorry I overlooked this email. Let me respond to your

RESPONSE: In general, I would say "Use corresponding positions. So if
you measure from the center of Point A, use the center of point B. Your
choices b and c violate this principle. This is a real-world problem
that most people completely ignore.

RESPONSE: I know (or believe) you are trying to find a contradiction in
my theory here. What I have said is that a Point is the smallest unit of
measurement accepted for a given purpose or application. So you are
treating the Point as being "unbreakable" for your measurement. So in a
sense the distance between any two Points A and B is from anyplace on A
to anyplace on B. But logic would dictate using corresponding locations
on A and B, and measuring from there.
Your discussions of b and c are interesting, but I reject both of these
