Turn time is the amount of time between the initiation and end of a turn. Turn type can be flip, open, or crossover / bucket. For open or crossover / bucket turns, turn time is from the hand touching the wall until the feet hit the wall. For flip turns it is measured from the beginning of the initiation of the swimmer's turn (when their head begins to go down) until their feet hit the wall.
The turn time metric is available for Gold level profiles only.
