Should I send another LOCI??

I have been waitlisted at my top 3 choices, and I really want to get off at least one of them. This week I was named valedictorian of my school, but I don't know if that is worth sending another update? I sent a LOCI back in early April/late March and it has been a month. I don't have anything else I could give an update on so it would just be about me being valedictorian. Is it worth sending?? Will it hurt if I do?
