I also still have my natty copy of the 'sliderule' he had sent out
with one issue of HFN. This seems to imply I should change to a more
powerful amp. I confess seeing this was one of the things that
prompted my curiosity and lead to the HFN article I mentioned. Like
yourself, I suspect, I've spent far more hours than any sane person
should watching a scope display, etc, of power amp output whilst
playing music to see what demands the music waveforms place on the
amp and speakers.

Some time ago John Crabbe reported published work in which listeners'
perception of the same absolute loudness was rather different when
they were listening in a large concert hall compared to a domestic
listening room. This would suggest you do indeed need less in SPL
terms at home than you get in the auditorium.

Because the nearfield and farfield are closer at home.

You may be confusing cause and effect with a situation where the same
mechanism is causing two effects. :-)

How large is your living room ?

I can assure you it'll be an issue for many Americans. ;~)
