Lots of places just use different wording and stay away from specific rankings. Basically student A is "good" and student B is "really good" and student C is "really, really good". kind of meaningless though, because they'll already know you honored x, y and z, got good evaluations in rotation Q, R and S etc. Most PDs aren't so focused on the grades/rank, and instead will focus on your Step 1 and core rotation evaluations, making these grade breakdowns pretty insignificant. I had a med school mentor who described the fact that med school grades really don't count for anything as the "dirty little secret" of med schools -- you need to learn the info, and having a grading system may foster that, but in the end the grades themselves are far less meaningful than the typical first or second year student ever appreciates.
