This is the initial phase of the Ruffles waveform, as a normalized angle. This is useful if you want the waveform to start at a phase other than 0°. Ruffle Phase is relative to Bend Pole Phase; in other words, it's the rotational difference between the ruffles and the poles. Note that this property has no effect unless Bends, Bend Depth, Ruffles, and Ruffle Depth are all non-zero.
