I'm particularly surprised that the stalemate = win rule doesn't result in more decisive games. Intuitively, it would seem that an entire class of endgames that are classically draws would become winning for the stronger side.
Perhaps computers are so strong they can "see through" the rule change?
From the posted stats, the Stalemate=win rule does result in more decisive games (fewer draws). But it has an even bigger effect in giving white a further advantage over black.
