Not only that.

Now that Gnu go version 3.4 came out a few days ago, you might want to
use that.  It is much more accurate when scoring than 3.2 ever was.

In a recent mail Gunnar Farnebäck, the guy that implemented scoring in
Gnu go mentioned that he had over 98% of a test database of 600
professional games scored within one point of the correct result.
Professional games are much more difficult to score than games from
NNGS or IGS since they are stopped earlier and not played out.
