In the real world, the power that a transmitter delivers to a non ideal

That may well be; I am no expert on this; and, the point has missed my
detailed investigation.

But, if memory serves me correct, when I fed a 50 ohm antenna with an
old 75 ohm PA, equipped with plate voltage and current meters, I would
have expected a dip (although it might appear slight) in voltage and a
rise in plate current--indicating, that indeed, I was feeding "more
power" to the load ... although not desirable ... extrapolating from
this, feeding a 75 ohm antenna with a 50 ohm rig, I would expect the
opposite.
