I think Paul is probably suggesting that you are comparing what is
grey on your monitor to a reference grey card. If they match and
you've set up your monitor properly, what is displayed on your
monitor should almost exactly match what is seen on another monitor
calibrated to the same.

Your method is pretty good, as long as you don't share images with
others. However there is a wide difference in how people see
colors, and relying on the your eyeball to calibrate is not the
best idea, since my eyeball may be different.

I am an iconoclast about this topic. I think most monitors don't
need a profiler. Here is how to tell. Open PS, open a blank
document and create a continuous B&W graidient. If you see no color
cast in the entire spectrum, from B to W, you can do an excellent
job of "profiling" with this procedure:

1. Set monitor color temperature to 6500 deg K (on your monitor).
Adjust to Maximum contrast

2. Adjust to Maximum brightness, then decrease until you JUST see
the difference in the two darkest squares of the black point boxes
here: http://www.epaperpress.com/monitorcal/title.html

3. If the grey boxes are ABSOLUTELY grey, you don't need to mess
with color calibration. Adjust gamma to 2.2 with your video card
(preferable), Adobe gamma, Little CMS
( http://www.littlecms.com/profilers.htm ),

or QuickGamma http://quickgamma.de/indexen.html . Best way to
measure Gamma 2.2 -

, set at 2.2 and adjust until the boxes blend at a distance or with
a squint in dimmed lighting.

You are done.
