Don,
I have figured out the discrepancy in the average game length. As
playout length I count from the start of the game, which gives me
114-115. I believe you count from the starting position where the
playout starts. Because when I modify my code to do that I also get
111 moves per game on average.
But I believe counting from the start is more meaningful if you're
going to use the game-length as a reference number. Because otherwise
you might get a different number depending on how explorative your
search is. If your search tends to explore deeper lines in favour of
wider lines you get a different number. Or at least you'll have to
include the exploration-factor K in your UCT tree as a criteria.

For one thing, komi is different. I used 0.5 for running this
test.
I would have use 0.0 but some implementations don't like even
komi's.
But the komi should have no effect on the playout length. I started
out with 103 moves, but that was because of a mercy-rule. Without it
it's 114. You have 111 rather consistently. And I assume you don't
use
a mercy-rule. Nor super-ko checking, is that correct?
The score is what I was looking at, but you are right about the
play-out
length because the play-outs don't care what komi is.
Do you use the 3X rule? Have you checked the other specs?
My guess is that your playouts are not uniformly random - that is very
easy to get wrong. Of course that is just a wild guess, it may very
well be something completely different.

Another thing I have never looked at is AMAF. But that also shouldn't
affect playout length I assume.
By the way, thanks for all the pointers to 'git from everyone.' It's
new to me and at first glance the specs look good, so I'll definitely
give it a go.
