He seems to have discovered yet another type of distortion which he has
christened Dynamic Damping Factor Distortion (DDFD).
Well, the DF does change during a wave cycle. Ra isn't constant at all
points; if it was, there'd be less THD and IMD.
It sounds to me like you are saying this isn't really a new discovery, but has
always been part of the known THD and IMD.
