Sorry, that's not my department.  I just toss out stupid
comments and guesses that are so ridiculous they trigger
other people to finally jump in with the right answers.  :-)

On my screen I measured a far point separation of about 85mm
and an image width/aperture spacing of 80mm.  That's roughly
proportional to 1.26mm OFD on a 5P image.  My WAG: he used a
very small stereo base.  But I have no macro experience and
you do, so I presume you can't make the math work with the
MAOFD formulas, right?
