Relative complexity revisited

Long long ago and far far away in a distant galaxy, I came up wwith
the notion of relative complexity. Relative complexity of a comma,
with respect to a temperament, is found by wedging the comma with a
comma basis for the temperament, and applying a complexity measure to
the result. I was using geometric complexity, but we can, for
instance, use Graham complexity when it is applicable. Below I order
intervals within an octave (this measure is octave equivalent)
according to their Graham relative complexity with respect to
2401/2400, with the results 2401/2400 reduced. This gives us shells
and balls and scales again, if we want them. Below are the first few;
I note that the pentatonic scale from ball 2 and the nine-note scale
from ball 3 are epimorphic. With the 17 notes of ball 4 we finally get
a complete diamond, and the very same convex closure of the tonality
diamond I very recently presented.
