Parametric optimisation plot. Based on 6534 simulations on 819 C3D gait files, representing 10,910 gait events, four input calibration parameters (left side) led to find the lowest four output values (right side). Bullseyes help reading output values: for both Foot Strike and Foot Off, the closer the median and inter-centile values are to zero, the more accurate and precise the results
