I believe that a simple answer to the PM 5 Gamut Mapping might be:
1) Classic bases the max primaries off of a linearized balance, thus
reducing potential saturation of a heavy primary.
2) Chroma Plus was introduced to help hit a better saturated green
(c+y), which might be native to both ink jet and photo printers not
using ICC
3) Colorful was added when the Chroma Plus seemed a bit extreme for
pastels, skin tones and a few other memory colors.

David,
I own ProfileMaker 5.02, and I still have not been able to sort out
exactly
in which way the engineers at Gretag Macbeth intended the three
available
Gamut Mapping choices (Logo Classic, Logo Colorful, and Logo Chroma
Plus) to
affect the resulting profile.

I tend to think that each new gamut mapping method allowed mapping out
of
gamut saturated colors closer and closer to the outer boudary of the
device
gamut, selectively or intelligently desaturating colors instead of
globally
desaturating colors by the same amount, as was used to be done in the
past.
