> The Improvement Factor is an average of the Voltage Output and the THD output. It gives you a factor of how much the AC power is improved by the P20.
Which also doesn't make much sense to me. So the lower the THD, the less improvement? And averaging that with the 120 V output? So the 230 V European version has a higher improvement factor?
I think the measure goes like this: the higher the dial, the more you feel you are getting your money's worth out of your 10k usd purchase. it's a fantastic feature, really
