First again (and I hope for the last time) I understand how you can
say that all losses are ultimately resistive, BUT is is iportant to
use the proper terminology for each of the modes of loss to be able
to discuss them individualy and to have any hope of eliminating or
atleast reducing them.

I'm glad you acknowledged that power facter is related to energy
losses in a capacitor, I havn't seen the equations since back in
college, nice to have it refreshed in ones mind.
