Here is the class profile which has a separate section for ED students. https://about.lafayette.edu/lafayette-at-a-glance/class-profile/ Laf takes about half of its students in the ED round so applying early should certainly work in your favor. Good luck.
As an aside, I see you have a post from a few weeks ago saying you are applying ED to Bucknell. http://talk.collegeconfidential.com/bucknell-university/2102317-chances-at-bucknell.html#latest I certainly hope you are not applying ED to more than one school.
