Bob,

I don't think this is a ridiculous idea, there are just a lot of
problems
that must be solved first before it can be done correctly.  Just because
it hasn't been done well yet doesn't mean it cannot be!

I seem to remember you are right about the Elo points.  I think at one
time there was a much larger difference but some gradual adjustments
have been taking place over the years.
