Switch Version.
Mistakes were: 1 early turn in Hospital due to a dropped 'Up' input and forgot to close Drugstore menu early after buying final Hikobari. Probably about 2 seconds collectively.
Bad RNG was: 3 Hospital encounters, 1 encounter in Arcade trying to head out to the World Map at end, 2nd try Ghost.
Good RNG that somewhat countered that bad RNG (mostly 2nd try Ghost) was I did not get an encounter heading to the Park, which is pretty rare.
Overall happy with getting the first sub 16, but probably done with this now. The run is kind of garbage and largely entirely about luck.
