what, this? it'd work fine. for impedance analysis, voltage sources can be treated as short circuits. real power supplies try hard enough to be short circuits that they can be treated as such. the source would see R1||R4 across its output at ac, and high resistance at dc

it seemed more like 40% than 50%. just spitballing
anyway, you can only estimate rms from peak if the waveform is a proper sine. that waveform is too irregular. do the actual rms math instead. pretty sure you've got a hardware multiplier, if not, use a look-up table to calc the square
