I don't see that as smooth at all. Smooth would be curved peaks and valleys like the surface of the ocean.

Doug, the reason it doesn't look smooth is because of the extremely high resolution of an IAC. I'm not sure of the exact specification but it can literally make "hundreds" of minute adjustments per second. If one could average all of those adjustments down to one per second, it would likely give you a basic waveform. The vast majority of modern production cars control idle speed with an IAC.
