I would be interested to see a study of win/loss/draw as a function of ability
over a large span of games.  It is probably also a function of the player
involved, I would guess, and probably also the competition involved.  I would be
pretty surprised if the three outcomes are equally probable.  It is pretty clear
that starting as white is an advantage (exactly one tempo).  What does this
translate to in terms of scoring?

If you read my other posts on this topic, you will see that this is the point I
was trying to make (in a back-handed way).
