Model performance. Performance Error (PE, %, closed circles, group 3.5% after 3.5 min = A; group 5% after 5 min = C, and group 6% after 4 min = E) and Absolute Performance Error (APE, %, open circles, group 3.5% after 3.5 min = B, group 5% after 5 min = D, and group 6% after 4 min = F), with their respective linear regression line (hatched), polynomial fit (grey line), and median performance error (MDPE, continuous black line, A, C, and E) and median absolute performance error (MDAPE, continuous black line, B, D, and F).
