Rail,
Have you ever played a course set up by the PGA tour? She's facing quick, firm greens, narrowed fairways and more length than she's ever seen in a tournament. The "average" tour pro that's shooting 74 and missing the cut would shoot 66 with his eyes closed on the average course from the back tees. I've played in a couple on national amateur events and it's no comparison when a course is set up for a big event. None at all. And I'm not talking about a major, that's a whole different deal. She wouldn't sniff 80 on a US Open course.
