If I didn't know, I likely would stay in the battle because I'd think we're both maxing out our 40 AP, 20 HV, 1 CV and promises. If I did know, I'd be tempted to look elsewhere because I know you're putting in(or could put in) twice the AP. I think lack of knowledge is a win for EE teams.
I really think the less we know about one another's resources, the better. UNC has no idea what sort of effort Duke is putting into a player in the real world. In HD, we know EXACTLY how much another user can put into a recruit.
