What this metric measures
Centre offset must state whether the result is metric distance, calibrated plane distance or a normalised image proxy. These forms are not directly interchangeable.
How Trampoline Lab calculates it
Preferred methods map body centre or foot position onto a calibrated trampoline plane. A fallback may use normalised image coordinates when scale is unavailable.
How to interpret it
Use the trend and landing-zone pattern to understand drift. Thresholds must scale with trampoline size and valid visible area.
Limits and responsible use
Camera movement, perspective, trampoline detection error and multiple athletes can invalidate the estimate.
