Well, if without the breakin code turned on gnugo makes overplays that
leave weaknesses that it doesn't see, and never gets punished for it, and
with the breakin code turned on it plays slower, more solid moves, it's at
least possible the breakin code would make it look weaker against 3.2 (or
3.3.23 without breakin).  So perhaps we shouldn't be surprised that it
doesn't help against 3.2?  I agree though, it would be nice if it helped
against earlier versions.  I think, however, that play on nngs and replays
of games would suggest that the breakin code helps against people.
