Two of my recommendations came from 0-7's. Both of them have known me my entire life, but I had to sit and chat with them when I finally decided on the Navy route and they grilled me. It was intense, but they are awesome people. If you didn't know the person I think that star (or stars) would be terrifying at this point.
A funny story about stars. During PLC-Jrs in 2010, our platoon was standing outside the PX in the pouring rain one morning. One candidate (our resident moron) was on door-holding duty. He's doing fine until a freakin' 3 star roles up with an entourage, and the candidate gets tangled up in his poncho trying to open the door for this general. He gets so flustered and tangled that the general eventually gets fed up and opens the door for himself, at which point the SIs from the entire company proceed to obliterate this kids soul for the next 30 minutes.
Oh how I can't wait to go back to OCS...
