( If I did this right,) the scale is created by keeping all the white keys/notes the same
but lowering the black keys/notes by 39 cents.

Why even use this scale at all?

1) It has a number of chords (with perfect 5ths) that don't exist in 12 EDO.
2) It is very simple to play.

Just some of the chords available:

C major
C minor
C subminor
all the above with a Harmonic 7 th
{11 th harmonic also exists if tonic is C}

D semi-augmented minor (tonic @261)

F major
F subminor
the above with the 7th harmonic

F semi-augmented major (tonic @561)

G major
G subminor
{11 th harmonic exists if tonic is G}

All the above is correct I hope. I know there are other chords here, but this gives you
a general idea. Sadly, some common 12 EDO chords have been destroyed to create all the
new stuff. You had to expect that.

There's nothing much like it in Scala's scale listing.

Here are chords going around the circle of fifths; the first column
are major thirds, the third column fifths, and the fourth column
sevenths. The second column is the minor third from the major third to
the fifth.

[400, 300, 700, 1039]
[439, 261, 700, 1039]
[439, 261, 700, 1000]
[439, 261, 700, 1000]
[439, 300, 739, 1000]
[400, 300, 700, 961]
[400, 300, 700, 961]
[400, 300, 700, 1000]
[361, 339, 700, 1000]
[361, 339, 700, 1000]
[361, 339, 700, 1000]
[361, 300, 661, 1000]

We have three 12-equal triads in a row, with two of them having an
improved value for the seventh. This is followed by three triads where
the major and minor thirds are of an intermediate size, and then a
wolf flat fifth chord. Following that is another 12-equal triad, with
a sharp seventh, and then a supermajor triad/tetrad, the seventh of
which is sharp if it is supposed to be a 9/5, and is more plausible as
a 20/11. We have two more supermajor triads with 12-et 1000-cent
sevenths to go with them, and the whole thing wraps itself up with
another wolf fifth, the 439-300-739 chord can be taken as a "ratwolf"
351/350-magic triad of sorts. If we knew what intervals you wanted it
would be possible to optimize this.
