This doesn’t suprise me.

I think a more important question might be (and I think P.J. might have been alluding to this) Is how much training should be aerobic vs speed vs speed end vs special end. when training a 400 runner. This is really what I’m interested in.

Yes! Exactly right. There is no way the aerobic “contribution” to the 100m explains the amount of aerobic type work that has been found to be useful in preparation for it. Same goes for the 400m.
