Interesting to think about this in the context of the Chinese gymnasts. Let's assume, for the sake of argument, that the Chinese girls were under 16. On the face of it, at least, there seems to be some tension between being for acceleration in the case of baseball but against it in the case of gymnastics. Not that the two cases are exactly analogous, nor that anyone here has expressed this combination of views. But still, perhaps it's worth thinking about the two cases in relation to each other.
