18% gray is not a myth. It is just that most people do not understand
where it comes from. If you go out and measure thousands of scenes with
an averaging meter, the average of those exposures will come out to 18%
gray. So 18% reflectance is an average value, where you want to put that
average value in your particular photo is up to you. It certainly is not
cast in concrete (which is usually near 18% gray, by the way <grin>).

I agree. The idea that you have to use multiples of the printer's
stated resolution (itself a mythological beast) is another
photographic myth, like 18% gray.
