I'm not sure what you mean by "top the Green List". The list is
ordered by ICC rating, so if crafty were a "green" program, it would be
top already. I think the R(MHz) figure isn't to be taken as anything
more than giving a general feel for the influence of clock speed.

I think the Green List is great, as was its precursor the "Under 2600
List".
