hey george, take a look at this curve:

if

i left it unlabeled for your fun and amusement . . .

(if you don't like seeing all those tiny local minima, not taking the
exponential should help . . . let me know).

anyhow, the global maximum here is at 67 cents.

the next most discordant intervals are kind of in that vicinity, but
don't form a contiguous region the way they did with the original,
smooth harmonic entropy formulation.

then, the next most discordant interval (within the octave) is at
1139 cents.

then more in the vicinities of 67 and 1139, with the caveat above.

then, 758, followed by 757, followed by *750* . . .

let me know if these values are ok for you . . . if not, there's
plenty more that can be tried on tomorrow's menu . . .
