Don't know if anyone is interested but I got this little snippet in the

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.
