I don't know, the above could very well be true. However, keep in mind that schools post their average stats of matriculants. A couple people with lower stats can really drop the overall average, even if dozens more people have stats well above that average.
I have always been told that if your numbers aren't above the average, then don't bother applying. I don't really agree with it, but I don't think it's entirely bogus. If the only difference between you and other applicants is numbers, then they're going to naturally take the person with higher numbers; those that get in with lower numbers usually have something else to make up for it, whether it be great LORs, awesome volunteer experiences, research, etc.
