You are right, but I think that you may also be misconstruing the nakade problem as a lack of concern about margin, when it is really a fundamental failure to understand (i.e., failure to explore sufficiently) the nakade shapes. The tendancy for your final scores on lost games to be 0.5 really reflects a motivation on your own part to lose by the smallest margin that you can. After a point when the game is resolved, this doesn't conflict with the program's goal, so it lets you do just that. As an interesting thought, I think that it might actually be informative for people to try out programs that _do_ try to win by exactly 0.5! Not as a fundamental goal, but rather as a slight preference for the endgame. If authors can do this in a manner that does not degrade the playing ability much, then human players might be able to see even more clearly what life & death errors a program makes, and at what point it is able to discover the correct solution. Clearly the programs would be weaker like this, but I think it could expose some systematic problems very quickly, so that they could be focused on.
