"Critical" coupling is a coupling that achieves that which is desired in the
application involved.
Thus "critical" coupling varies dependent on the situation or application
involved which in your
'specific ' application may well be defined as you stated but is not all
inclusive..
That's how I see it and what I spoke of is confirmed by NEC and by personal
experimentation
If you choose to disagree that is your choice but goes directly to my
statement regarding quoting
of text without full understanding.
I have no interest in argueing the fact, try somebody else.

Art said elements are "critically coupled". Critical coupling is defined
as maximum energy transfer at the resonant frequency.

Coupling additions (more loads) to a feedpoint lowers the impedance
unless additional measures (transformations) are taken. Coupling more
loads to a feedpoint is tantamount to paralleling resistors. Terman is
right.
