Yay! Free bug-fixing! I love this list.
Actually, I have that script sitting on my computer since some time in
2002. I didn't write it: it was written by a friend of mine and posted
to the college unix users group mailing list, with comments as to what
the proper scaling factors are all around.
The scaling factors for the various components were chosen at that
time because it seemed to be good, realistic numbers to compare
performances of then-current desktop boxes. At least *we* felt it
works better than bogomips.
As to the part of looking at used memory instead of total memory: I
don't remember it doing that, I have to go back to check. The double
counting of scsi disks is a bug, mostly because this script was
written before UDEV when it wasn't an issue.
Lastly: this is just some good, not-too-clean locker-room-style fun.
Don't take it too seriously!

In this course we will of course make use of God's Units, namely
h-bar = c = 1
but occasionally I will indulge myself in my personal addition to
those units, in the form of
2 = -1 = pi = i = 1
please feel free to interject whenever you feel confused, and I will
make my best effort to clarify things.
