For every 10 participants, there must be one designated instructor.
Each instructor must be allocated a specific group of participants who are to be positioned in a clearly delineated area assigned to that instructor. This can be done using colored clothing, or by using a clearly marked area.
Each instructor must supervise their group during the attempt to ensure full participation and monitor if anybody in their group leaves the area.
The instructor must note any participants who need to be disqualified from the final total either for non-participation or for leaving the allocated area before completion of training.
