A Round Robin teams event may be conducted using the Swiss teams.
At the beginning in each session you define the draw for teams in the event. This allows you can report on and produce results for each session of the event as you do in a Swiss teams event. Each time a session needs to be defined, select the manual option rather than the automatic Swiss draw option.
You will then be required to manually enter the draw for each session of the event. Odd numbers of teams can be handled in the same way as they are in Swiss events.
