The question?  Oh, you mean your question.  I answered that in my
paragraph which you fortunately quoted just below your question,
namely:

I have indeed checked the power draw.  A 2011 iMac here draws 81-90W
while fully awake and 54-63W in display sleep.  It draws essentially
0W when fully asleep.

So, putting the display to sleep saves only about 27W.  Putting the
machine to sleep saves at least another 54W.  That's why I want the
machine to sleep rather than to just be in display sleep.

I have in fact it set to sleep, yet it doesn't sleep automatically for
some reason.  It only goes into display sleep, so I put it to sleep
manually, but I hate to have to wake it up to do so (sleeping pill,
blah, blah).
