I think in 7x7 it's possible to build the perfect book. It's not possible in 9x9 of course but it would be fun to try.
Unfortunately, CGOS is not set up to accept draws - I would have to rework the server a bit. When I get some time I will look at the top players on CGOS and see what the win percentages are - unless someone beats me to it (the SGF files are free for download.)
