 Formerly in the Swiss Football League, teams played a double round-robin, at which point they were split into a top "championship" group and a bottom "relegation" group; each played a separate double round-robin, with results of all 32 matches counting for ranking each group.A similar system is also used by the Scottish Premiership and its historic predecessor, the Scottish Premier League, since 2000.After 33 games, when every club has played every other club three times, the division is split into two halves.
