I dont think the prop "tach" sensing device would care. My understanding 
of how this thing would work, intuitively...:
 
The user sets the prop speed "baseline" based on whatever value he wants 
(engine RPM, separate optical tach, seat of pants sensation, etc). The 
Constant speed unit would detect whatever it detects at whatever rate it 
detects it at, and varies the prop pitch based on its program to 
maintain its detected baseline.
 
It matters not if it gets 1, 2, 3 or 10 "pulses" per RPM, all it knows 
its going to try to maintain whatever amount of pulses its told to 
maintain. In doing so, the prop maintains its set RPM.
