Yes - I agree - but having a second 'formula' to allow for the experts
to race honking great machines with multiple RCX's and a dozen motors
would be nice.

Most people don't have access to plotters. The most likely thing that
everyone will have would be a standard ink jet printer with A4 or
Letter sized paper.
I think the idea of using the grey scale value to indicate your
position on the width of the track is a great idea.
It allows for beginners to use line-following code to "get something
going" - and allows experts to do things like measure the rate of
change of brightness to figure out when they are on a turn and to
work out their tactics accordingly.
With only one light sensor, you can only measure one parameter -
having that parameter be your position on the width of the track
seems to be the most useful thing for both beginners and experts
alike.
IMHO, the rules should specify a minimum track width, a minimum
turn radius - and just tell drivers that the entire track will fit
within a 2'x4' space.
Don't forget to add some rules about the maximum length and width
of the robots.
