Forgive a dumb question, but doesn't George's RPM number refer to the number of 
flashes of the strobe per minute? If so, then it does make sense as everybody 
said, that the highest number of flashes per minute which showed a stationary 
marked blade would give the actual number of RPMs of the rotating shutter, and a 
halved strobe speed (575 in this case) would give a harmonic of the speed. But 
this wouldn't imply a harmonic at 2300 would it? Instead it actually shows a 
"half-rotation harmonic", no? Just curious, since I don't even own a strobe.

Lew, full of technical-sounding but basically dumb questions today... :)
