Well, you're right, and maybe not. A 30 equates to 710, which is the upper limit of the middle 50% of the class. So ...25% of the class score above 30, and 25 about 620 ...so yes, scoring 25 and up would seem to get one in the hunt. But in this specific case, more was needed to get beyond just being considered, and as the CGO indicated that meant 30+. Like saying ..."I drove the posted speed limit of 55 ...so how'd everyone else beat me here?"
Again, this reflects the reality that USNA has different admissions requirements/standards/expectations for different groups. One size does not fit all, and looking at the profile of the entire class provides averages for a non-existant grouping. The bottom line? If one falls into a non-priority grouping, to be competitive (generally) one had best look @ the very top of the score ranges to stand a fighting chance. Again, generally. Doubt this contention @ your own peril. Especially when USNA is singing the same song, if in a different tune and ms vs. mf
