Small Generator Shoot-Out Results

I think if you had them on an oscilloscope, you would see a smoother slope/curve from the PH, ( until you zoomed in on the digital micro s stepping of the wave form) but also a higher voltage peak which is the reason for the lower PF reading

While the king is a true synchronous rotating mass generator, the peak voltage is not as high, but the magnetic field and current are more evenly distributed, over the power cycle
Just my opinion
