You may want to reset one or more event results from a Database in which some events were run. By "reset" we mean remove any Result information for all rounds of a selected event. If you have "accidentally" run an event(s), this is a great way to reset those events for the meet.
From the Main menu Bar, click on File / Purge / Reset Event Results Only. From the event list, select the events you want to reset and MM will remove all results and scores for those selected events and reset the event to Seeded. This will not remove the entries nor will it remove the first round seeding.
