I would agree, mine was more along the lines of why I wanted to be an officer and how I will use my enlisted experience to lead. I also hit on my age and humbling ASTB scores. A 4.0 and 9/9/9... good grief, I'd say that persons study habits are pretty solid.
It's such a huge difference for people like myself going through the process having not done a mathematical or engineering degree to then test 7 years later. Compare that to younger people with math-heavy degrees and it's a different story.
I think that's why we don't see a hard cut-off for GPA and OAR is barely looked at, it doesn't really tell you more than how much did they study in college. GPA ultimately comes down to a measure of applying ones self for a period of time, not intelligence or aptitude for military service, fortunately.
