Are Average SAT Scores Reported By Universities Superscored?

I was searching on prep scholar for the average SAT scores of students admitted to universities that use the superscore policy. I was wondering if the reported 25th, 50th, and 75th percentile scores are superscored or not. Would this affect my target score for individual tests?

This is my first post so I hope this discussion is in the right location.

The EBRW and the Math scores reported are the highest ones for the accepted applicant.

As an FYI, each school’s Common Data Set reports the 25th/75th EBRW and the Math scores separately. Prepscholar incorrectly adds those 2 numbers together attempting to give a 25th/75th percentile out of 1600, which one cannot do with accuracy based on info provided.
