Permissible Kata Repetition

Kata performed in following rounds must follow the permissible kata repetition rules.

A-B-A = The competitor must not repeat the same kata twice in a row. e.g. If the competitor performs a kata (kata A) the next kata they perform must be a different kata (kata B). After performing kata B they may then perform kata A again or the competitor may also choose to perform a different kata.

Note – If a tie breaker kata is required to be performed than the same rules will still apply. The kata performed for the tie breaker must be a different kata to the previous kata performed. If successful in the tie breaker then a different kata to the kata performed in the tie breaker must be performed.

A = The competitor may repeat the same kata in each performance.
