I am sorry to demonstrate my ignorance, but what are the "TERPS" and
where might I find them? I did notice that the AIM says that sectors
have to be no smaller than 90 degrees, so there can be no more than
four. It does not say the criteria for deciding when and whether to
subdivide the MSA circle.

In the case of RNAV approaches, there is only one MSA. It is not very useful
information, nor has it ever been.
