Main reason: Altimeter indication is corrected for barometric pressure.
First order of business before comparing is to set the altimeter to
29.92.


No. As Dan points out elsewhere, the main error in the barometer is not
correcting for non-standard temperature. There are other errors as well,
but none of them involve setting the altimeter to 29.92 in an attempt to
make the altimeter more accurate. Unless the correct altimeter setting is
actually 29.92, setting it to 29.92 will simply make the error worse.

Uh, yes. Brainfart on my side. Sorry
