Parallax generates a series of pulses of random width over some time period that gives an average voltage which is governed by the number you feed in.
The PWM output feeding Victors is one variable width pulse, approximateley 0.5 ms + (#/254) * 1 ms in width, with a repetition rate around 16 ms (the times are not far off, they'll do for illustration).
