Whoa Keith, Dr. Best's power equation that is being used
does not work for instantaneous powers. It is adapted from
the irradiance equation from optical physics which is a
*time averaged power density*. The irradiance equation
does NOT work for instantaneous powers even in the
field of optical physics and it is not supposed to.

Trying to use Dr. Best's power equation on instantaneous
powers is akin to trying to measure the feedpoint impedance
of an antenna with a DC ohm-meter. It is the misuse of a
tool. All powers or power densities appearing in the
power equation *must* be integrated over at least one
complete cycle. Instantaneous powers are simply excluded
from this energy model that we have been discussing.

Note that every voltage, current, and power in Dr. Best's
QEX article is an average value.

I have made absolutely no assertions about instantaneous
powers so your instantaneous power data is irrelevant to
my assertions. When I say "power", I am always talking about
time averaged power - never about instantaneous power.

You are free to make assertions about instantaneous power
but those assertions do not apply to my statements
about average power. They may be interesting to you but
have nothing to do with anything that I have been saying.
