Hi Sylvain,

Thank you for running that test!   It verifies my earlier results and
it shows that either 6.5 or 7.5 is as fair as you can get.   Presumably,
6.5 is unfair for white and 7.5 is unfair for black.  

If 7.0 is in fact the correct komi,  I suppose this test also indicates
that it's easier for black to win with 6.5 komi than it is for white to
win with 7.5 komi.   My test also showed that.   So I suppose 7.5 is
the least unfair komi.
