  Nice work!

  Some people might also be interested in:


(It's included in Pachi source tree, but is absolutely independent.)
Its main advantage is the ability to very easily start off testing
instances on many machines sharing the same NFS volume. But it's perhaps
somewhat less user-friendly.

  This is very interesting! I'd be intrigued to know how well this works
for you in practice, e.g. how many games are required for basic tuning
of few [0,1](R values.
