Set up the agreement
- Write the exact drill sequence and decide whether natural drops pause, continue, or invalidate the attempt.
- Let the participant choose an appropriate ball, surface, pace, and non-physical alternative without explaining personal limitations.
- Clear people, pets, traffic, fragile objects, stairs, and other hazards from the selected area before any timer or camera starts.
- Place the recording device securely; nobody should hold or adjust it while moving.
Evaluation rubric
- The participant follows the named sequence for the stated ten-minute duration under the prewritten drop rule.
- The clip remains continuous enough to establish the duration and sequence without exposing unrelated surroundings.
- Voters do not score speed, style, difficulty escalation, physique, or prior ability.
Edge cases to decide before starting
- The ball leaves the safe area: stop the attempt and use the written drop or restart rule; never chase it into danger.
- A bystander enters frame: pause privacy review and replace the proof only with that person's informed agreement or a new attempt.
- The camera overheats or stops: use the technical-failure outcome instead of demanding immediate repetition while tired.
Privacy checks
- Frame the drill area without street signs, house numbers, vehicle plates, school marks, or bystanders.
- Mute or replace audio when off-camera conversations contain names or private information.
- Do not publish a performance clip or use it for comparison without a distinct informed approval.
Ways to adapt this template
- Use a seated hand-control sequence with a soft ball or comparable object.
- Replace the clip with a live private observation when storing video is unnecessary and everyone agrees.
- Shorten the duration or simplify the sequence in a new invitation rather than lowering the rule after the attempt.
Safety and privacy standard
Apply the standard to “I can finish a 10-minute ball-control drill.”: participation stays voluntary, and people may pause, stop, or choose a safer and more accessible alternative without penalty. Never turn the activity into danger, humiliation, discrimination, sexual pressure, medical direction, illegal conduct, or financial coercion.
