Yes, I gather the assignments, given history and everything else, are
too random to make them meaningful in themselves.  But thanks for the
policy URL above.  I had looked at the ARIN site but hadn't gone through
the policy page.  There is no answer to my immediate question, but
several incidental questions that I had put aside are answered there.

I have good data on IPv6.  As soon as I put the IPv4 stuff aside I will
invest a few hours in digesting that.
