difference in the bump in Washington and Lee ED1 versus 2?

Anyone know the difference? Our school and private counselor advise that our son is a likely admit for ED1 but neither knows of the “bump” difference between ED 1 and ED 2. Does ED 2 offer a lower bump? He has his heart set on a school that is highly unlikely to admit him. We want to let him apply, but are concerned that this may be foolish if it will dramatically reduce his chances of getting into W & L, which is his second choice. .
