I'll look, but so should you. It is definitely published somewhere, because I remember ENT average match was 237 in 2004, and I was pissed that they beat us. But to say that no one knows is silly. The data are known. People match, and the NRMP knows our scores. It's just a matter of finding the article I read it in.
Read this in the meantime:
