Measuring that tiny amount of give follows a straightforward method. First, the rope is secured on a calibrated load frame. A known load is applied, and the resulting elongation is recorded in millimetres. The stretch percentage is then calculated as (elongation ÷ original length) × 100. This simple formula turns a raw number into an easily comparable metric.
