I noticed the same angle in the 9x9 study, more on Fatman, but also on Mogo.
To me it still seems to be an interesting coincidence (if that what it is)
that it happens about the level where a MC program (without a tree search)
levels off. On 9x9, it was around 1400 elo for Fatman and 1600 for Mogo. The
same seems to apply here.

It would be interesting to see a similar study with pure MC programs (no tree
search of any kind). And/or to get a few 'in-between' data points near the
corner. Or to make the MC simulations weaker/stronger, and see how that
affects the performance of the UCT programs... If I had all the machine
power, and nothing better to do...
