This flies in the face of most of what I've read in print, but perhaps I'm
not so well read. Is there a good reference to this topic that goes into the
relative merits of different calibration standards, particularly monitor
gamma. Or can any of you tell me what I need to know?

Usually a LOT closer!

I did a very informal test, but you decide if it's relevant. I'm a
photographer, so I have a Minolta IIIF color meter - very common to film and
still photographers. I took readings inside a Graphiclite view booth (non
dimmable) and temps ranged from 6000K to 5000K depending on placement. On My
Lacie 22 blue, which I calibrated/profiled yesterday to 6500K gamma 1.8, I
create a white document in Photoshop 6, and fill the screen with it and
measure various points across the screen. Temps range from 5600-5730K. I did
the same test with my Minolta IV light meter. I won't get into specifics
about shutter speeds and ASA, but the brightness of the incident light
inside the view booth (at the juncture of the backstop and the bed) was 2
full f-stops brighter than what I measure off that above mentioned white
screen. If I were smart I would have put a bright white sheet of paper in
the booth and read the light reflected off it, which might have yielded a
more meaningful number, but this was an informal test.
