But a similar comparison of the former and latter using AEIs would reveal a much different (comparative) outcome. Also, my guess is that CIs for yesteryear&#39;s elite stallions were nearly the same at today&#39;s (elites). Yes, it&#39;s true that today&#39;s elite stallions service far larger books, but why should this, in itself, cause the AEI disparity? &nbsp; </p> <img src="http://cs.bloodhorse.com/aggbug.aspx?PostID=646422" width="1" height="1">
