Linking this with a previous thread ("Altitude...") might as well carry the topic of Mexico 400s to its logical conclusion and include the women's data as well. Note they improved by even more than the men. I'd attribute that to the fact that they had far fewer chances at meaningful international competition leading up to the Games, so low altitude marks are poorer than their shape would have indicated.
