An overlap means two matches get in each other's way: they are on the same court at the same time, or a team has to play in two places at once. Slams does not block an overlap outright, but flags it live so you can move things around deliberately. Below you can read where overlap comes from and how to clear it up.
Why matches overlap
The day planner recognizes six types of conflicts. The most common causes:
- Court double-booked. Two matches fall on the same court and overlap in time. Usually there are too few courts for the number of matches within a time slot.
- Team plays at the same time. The same team is scheduled for two matches at the same moment. This often happens with a combination of group and knockout, or when a player is in multiple parts.
- Not enough rest. A team plays two matches too close together, shorter than the rest time you have set.
- Unavailability. A team is scheduled at a time when it cannot play.
- Knockout order. A final or semi-final is scheduled before the earlier round has finished.
Overlap arises both when generating automatically (time windows that are too tight or too few courts) and after a manual move where you place two cards in the same slot.
