Yes. This is equivalent to the draw = 1/2*win statement made previously, but the 1/2 constant is just a magic constant. The problem is bicriterion an draw = lambda*win can be justified for all lambda in [0,1] as the admissible region. In first round, against a 300 Elo points stronger program, draw = win (i.e. lambda = 1) is acceptable for the weak program, but only draw = loss (lambda = 0) is acceptable for the stronger. In the final round of a tournament where you only need one point to win (or move forward to the next round) draw = win is perfect. If you need two points the draw = loss is optimal even against a stronger opponent. One day this may become an issue in 9x9 (not in a foreseeable future in 19x19). I guess when this happens playing 9x9 won't make much sense anymore.
