Know the rules. Run smoother events.
Seeds are priority rankings you assign to strong athletes so they are placed on opposite sides of the bracket, preventing early clashes between top competitors and keeping the draw balanced.
- ●Lower seed number = higher rank (Seed 1, Seed 2, etc.).
- ●Unseeded players are placed randomly after seeds are positioned.
- ●Use seeds to separate champions from the same dojo or region.
Default bout duration is 120 seconds, but you can adjust per division. Common guidelines:
- ●Youth/novice kumite: 90–120 seconds.
- ●Senior kumite: 180 seconds (standard WKF).
- ●Kata: per performance; keep bout clock at 0 or minimal since scoring is judge-based.
A tatami is a matted competition area. Set the number of tatamis to match how many rings you will run in parallel—this helps scheduling bouts and balancing divisions across available spaces.
- ●Typical events run 2–6 tatamis depending on size.
- ●More tatamis = more concurrent bouts and shorter schedules.
- ●Align tatami count with available officials and rings.
