These numbers are approximate. Many MSPM sections were revised several times, renumbered, or rewritten by different authors.
Unfortunately, this information was not saved.
So 120 is a lower bound on the number of MSPM authors, and 838 may be about half the number of sections published.

There were 2103 author references, so the average number of authors for an MSPM section was 2.5.
No section had more than 4 authors: the distribution is:
