Single round = 4 dives per athlete; 2 dives in Round 1 (lower DD), 2 in Round 2 (higher DD); Athletes pre-submit dive list specifying take-off + somersault + twist combinations
Why people argue about this
People often assume that athletes have multiple rounds with different dives in each round, which leads them to believe they need to plan for a variety of combinations across two higher DD dives and two lower DD dives, when in fact, they only compete once and must choose from the specified list of dives provided by organizers.
