What is Dive number in Diving?
The code identifying each dive: digits for the group and the halves of somersault and twist, plus a letter for position. Example: 107B is a forward three-and-a-half somersault in pike; 6243D is an armstand dive with somersault and twist in free position.
Example: The scoreboard flashed 5255B — back two-and-a-half with two-and-a-half twists, pike.
