Each leaderboard shows the raw ranking of student throws in each age category. The judges will be periodically viewing the submitted videos to establish whether the throw is legal (free of wind assistance and measured correctly).

If a throw is deemed illegal, then that entry will be removed from the leaderboard by the judges and the respective student will be informed. The date at the top of each leaderboard shows when that leaderboard was last checked by the judges.

The winning 3 students in each age category will be the top ranking students when “Final Judging” is posted instead of the last judging date. Students may re-enter with new improved throws at any time until 28th August 2020.
