I'm on shaky ground now. I think by then we've gone right through the list and it's back to the Maj7 again, though I accept that's a weak argument on my part. One could also define it as ##13 and avoid the subject :-)

The simple(?) 9, 11 & 13 imply also the additional notes below them in the sequence, so 13 implies also 7, 9 & 11, though they're quite often omitted. I believe "add" means explicitely to only the named note, but I'm ready to be corrected on that. That still means that Cm7add11 has five notes in it.
