The old disc type meter only measured current regardless of voltage
And I'm certain that the power companies would not want to tip the
scales out of their favor by having the digital ones work any
differently (arguing on complexity and reliability of course)

This being the case how can the PF not affect the measurement,
If A x V = W  only if the PF = 1 ?
