The number get's multiplied by a small number and that result is microseconds between each rise and fall of the crank signal.
Trying to do any serial monitoring gives a garbage signal (I don't yet want to try multi-threaded coding).
The signal pauses very briefly after sending each value. Like zoomed way in on the oscilloscope brief.
