I was attempting to give this a try. The lowest flash duration I can get is 29ms, and the lowest strobe pause I can get is 50ms. These values are too high (it only results in a little over 12 cycles a second, so the flashing is clearly visible, although I do see how getting closer to the values you mention would fool the eye (traditional cinema is 24fps).

The strobe pause lower limit seems to be hardcoded (the field resets to it if you enter anything lower), but the flash duration is not (the LED just doesn't light up with anything lower than 29ms).
