Default Re: Full wave rectified RMS voltage

So I found an article on line that says to get the "Real RMS" value for a waveform on top of a DC offset, RMS = sgqtoot((Vac^2) + (Vdc^2))

And behold it is correct using the values measured on my Fluke for DC and True RMS:
sqrt(12.43^2) + (6.49^2)) = 14V = 0.707 Vpk.
