plot of 5-limit commas

I plotted all 5-limit commas for which

tenney complexity [TC] < 30
and
tenney-based heuristic error [(n-d)/TC/log(TC)] < 0.001
and
the comma is not a higher power of some other comma

who can explain the "woof" and "warp", or curved 'grid', apparent in
this plot?

here is the plot with the ratios of the commas written in:

/tuning-math/files/Paul/waterfall2.gif

the size of the font used for each comma was 16^(1-epimericity)
where the epimerity is tenney based and equal to log(n-d)/log(n*d).

one can easily imagine the epimericity 'contours' running across this
plot, though i wasn't able to show them as easily as i thought i
would . . .

anyway, i hope herman miller, at least, takes a look at this!

I'd start by taking ratios of commas along lines, and see if there is
a single high-quality comma behind the line.

No; the lines are essentially single numerators in one direction, and
single denominators in the other.
