Isn't this a good argument for W/L/D tables?  What I would _really_ like to have
is a full set of 6-man W/L/D tables, plus DTM tables for the complicated endings
that I just posted.  Once the full 6-man set is generated, it should be pretty
simple to just run through and convert each to a W/L/D.  Of course, Eugene seems
pretty busy these days :)
