Wow, I'm daft then! Oh, well, it's music. It's art, not science, it
doesn't have to make sense. :-)

Ran into this while verifying what you said:

It gives different octave numbering systems. ALL of which switch at
C. The two midi systems it gives are Note 0 = C-2, and Note 0 = C0,
giving middle C options of C3 or C5, omitting entirely the possibility
that C4 is middle C.

Sounds to me like the old wonderful thing about standards, that you
have so many to choose from, is REALLY in play here.

Anyway, thanks for coorecting me, Luis!
