I don't think anything is eluding you. Some of the data is just
wrong.

Assuming that the film was shot with a spring-powered 16 mm
movie camera, the most common in those days, most had at least
two filming speeds. Silent was about 18 fps on most of these
cameras, and Sound was 24 fps. Shooting at Sound speed did not
necessarily mean you were recording sound at the time, but that
you had the possibility to add it later.

I haven't looked at that film footage in years, but I don't
recall any breaks in it. Maybe I'm remembering wrong. Most
spring-powered cameras of that time period could run less than a
minute on one winding. You'd shoot a bit, pause and wind the
motor, then shoot more.

Your calculations above have a major mistake, though. You are
dividing 9144 by 16. That's the _width_ of the film, not the
short dimension of the film frame. A 16 mm film frame is about 8
mm top to bottom including the between frame space. So you
should be dividing by 8.
