    Ok the issue in the end was embarrasingly simple...I was using a meter that wasn't true RMS, therefore my readings are out of whack.

    I've just ordered up a true RMS multimeter (a uni-t UT61E, mainly becuase the U61D fared reasonably well in this shootout.... *especially* for its 'true RMS' reading ability 42m30s in)
