"WebPeak-to-Valley (PV) and Root-Mean-Square (RMS) are two common parameters used to measure the difference between an ideal optic surface to the actual optic surface. Historically the PV is used more often than RMS but RMS is a much better method for measuring the feat of an optic. " - Peak valley ratio
