Combined levels: partners' combined ratings can't exceed the team level, partners can't differ by more than 1.0, and there's a minimum individual level (for example, 3.0 for a 7.0 team). Sections may limit roster sizes and how many players can be rated below the team level, and some offer extra local formats.
