As far as having enlisted family members, my class had the daughter of a former MCPON, and she got her first salute from him.
Boy do I remember that! She still comes up in conversation.... All I can say about that in public forums is that it REALLY helps to have family in high places.
Well.... if your locker and knowledge are solid AND your class team wants you to pass, you will pass. If they don't think you're ready to move on, you will fail. It's that simple. If your shit ISN'T right, then you won't pass anyway. But if your shit is right and they don't like you, you won't pass. They can ALWAYS find hits.
RLP is purely subjective (the locker and knowledge are certainly required, but mostly a dog and pony show).
BELIEVE it.
I'm 100% behind the above. I personally watched my DI pass up at least 3 hits right under both our noses. The guy really liked me, since I was able to stick it out for 3 days with 5 large hemorrhoids that later needed surgical removal and a 3 week recovery at home. Once I came back, I went through the Saturday bonding all over again, and showed my new class just how loud "loud" was.
Not saying I was all that, because I certainly wasn't, just saying that attitude is everything, and it really is a subjective measure by the class team.
Also, as a Candi-O, while grading my second RLP, I watched two drill instructors lock eyes, and one made the "throat-cut" gesture. The guy failed.
