Everything in recruiting translates to point values. I think there are certain levels where a scholarship email is triggered - say, for instance, if you take a 5 'point' lead in recruiting, you'll get an email saying you're in the lead. When your friend lost the lead, he got an email (it was close, say it was just a 1 point lead). When your friend dropped to 5 points down, he got another email. As he falls further behind (10 points, 15, etc), he gets more emails.
My $.02 on it at least.
