10-second single-leg stance + progressions — London, England.

London, England is the headquarters of BMJ Group, already confirmed via WebFetch to Wikipedia earlier this session -- which publishes the British Journal of Sports Medicine, the exact journal this standard's foundational citation (Araujo et al. 2022) appeared in. No honesty-limit caveat needed: BMJ is the direct publisher of the citation's own journal. Distinct from the existing Rio de Janeiro tile, which is built on the CLINIMEX Exercise Medicine Clinic's own literal origin cohort rather than the citation's publishing society; also a genuinely separate reuse of London/BMJ from this session's earlier functional_movement_quality_screen tile, which connected to a different standard's own distinct BJSM citation. A two-minute test that exposes a trainable balance deficit before it becomes an injury.

$180 proposed

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

Best of 3 one-leg holds per leg with safety support available + pass/fail at 10 s per leg + any eyes-closed/tandem progression + setup photo

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

• flat non-slip floor
• stable surface within reach for safety
• stopwatch

Steps

1. 1. Position the person near a wall/rail for safety; arms free at sides.
2. 2. Instruct: stand on one leg, place the free foot on the back of the standing calf, look forward.
3. 3. Time how long the position is held, up to 10+ s; allow 3 attempts per leg; keep the best.
4. 4. Record whether 10 s is achieved on each leg.
5. 5. If 10 s is easy, progress to eyes-closed or tandem stance and note it.
6. 6. Photograph the setup; log per-leg hold times and the pass/fail at 10 s; sign it.

What counts as done

• Best of 3 single-leg holds per leg with a safety support within reach
• Pass/fail at the 10-second threshold noted per leg
• Any progression (eyes closed / tandem) recorded; setup photographed

Proof is measured against these, not judged by taste.
