The allocation of lanes, changing with each round, is a feature of F3J, but can be used for other competitions having a duration task.
The Swap Lanes button on the Competition setup sceen is enabled at the end of a draw where lanes are used.
This brings up the Swap Lanes screen that shows, round by round, who flies from each lane.
The lane allocation may not be ideal if there is a mixture of team sizes and the number of lanes is less than the number of teams.
In this case, use the 'Swap Lanes' screen to make your adjustments.
You can focus on specific teams by entering team numbers in the 'Team Filter' box.
Alternatively, you can simply change the lane numbers in the Scoring screens.
Any changes made will be reflected in the Draw reports.
