Listings in the SAEM residency catalog (http://www.saem.org/rescat/contents.htm#startCatalog) include a line that says "Number of residents and position in match." Most programs list just one number, the number of residents in each class. However, some programs list two numbers. The listing for UCLA-Harbor, for instance, reads "R1: 13 13 R2: 13 13 R3: 13 13". What does this mean? That they match their top 13 choices for 13 spots? I know Harbor is a top program, but it seems improbable that not one of their top 13 applicants would have ranked another program higher.
