The note immediately following a koron is sometimes (when the

not all) Persian musicians)) lowered by about 20 cents. This is
not
notated, but considered part of the scale tuning. To accomodate this
for
getting better sounding MIDI I've introduced the "vlat" (append
'v' to
the note) to indicate this. Actually this note should also get a
strong
vibrato, and the vibrato and low tuning are perceptually
integrated
(serialism!).
I think there may be no need for special note for this, as it merely
indicates a cancellation of the intermediate pitch relative the
diatonic notation system. That is lowering a note with a koron this
way is the same as writing it with a sori and cancel it. This is in
fact how Hormoz Farhat writes it, like for the note below the finalis
in Dastgah-e Bayat-e Esfahan. It will work in any tuning, also E53
(Pythagorean tuning).
Details with your cent values:
The sum of the koron and sori intervals are always equal to M-m. Since
you have decided to use E12, M-m = 100 cents. And you set the koron
lowering 30 cents, and the sori raising 20 cents. So lowering a note
with a koron with 20 cents is the same as writing it with a sori and
canceling it.
