One factor that might be relevant is that I'm pretty sure the "bubble" is rather "deep". That is, there is a large number of applicants in the range from just below to just above the cutoff for admission. Thus a slight advantage to anything (including legacy status) could lead to a significant change in the mix of accepted applicants.
