When you import swim times, the import is logged with the date and name of the member importing them.
This is useful because it allows you to delete imported times in bulk if you made a mistake for example.
Click on the date to view all imported times for a specific import.
If the import contains relay results, an "Imported Relay Results" section appears below the individual swim times. It shows the event, team, matched or source swimmer names, result, position and any split times supplied by the results file.
Click on the pencil icon to edit an individual time, and click on the bin icon to delete an individual time. Imported relay results are displayed as complete team results and do not have individual edit or delete buttons.
Click the "Delete" button at the top to delete the whole import, including its individual times, relay results and relay splits.
