Setting the duration of a booking slot
You can set the duration of a booking slot at two levels.
Per lane group (recommended)
Go to Shooting range & lanes → Lane groups, open a lane group and set the Slot duration field (15 to 120 minutes, in steps of 15). This way, for example, your 25m lane can have 30-minute slots and your 100m lane 60-minute slots.
General time slot configuration
Go to Booking settings → Time slot configuration to set a global slot duration. This is only used if a lane group itself has no slot duration set. If there is no global value set either, the system falls back to 60 minutes.
