Predicted vs. observed values for the 90 participants using the Random Forest model. Top-left: Static–Flamingo; top-right: Static–Balance beam; bottom-left: Dynamic–Flamingo; bottom-right: Dynamic–Balance beam. The dashed line indicates identity (\(y=x\)). Numerical performance (R\(^2\), MSE) for each condition is summarized in Tables 2–3.
