<p>I hadn’t realized that the “54% of Harvard admits had a 4.0 unweighted GPA” was from self-reported data. You do realize that there is likely to be a small bias on the high side inherent in a self-reported statistic like that. Unless there is similar data that is derived directly from official high school transcripts of admitted students, I’d say that it is unlikely, then, that more than half of Harvard admits score a 4.0 unweighted GPA during high school. In fact, the structure of the data strongly suggest that many of the students queried gave a rounded GPA in answer to the survey, and thus, you have clustering around 4.0, 3.9, 3.8, etc.</p>
