¹Ratio of mean velocity/max velocity (optimal score ∼0.53). ²Accuracy of reaching the middle of the target (perfect score=0). ³Measured area of circle (the higher the score, the better). ⁴Measured ratio between the x and y axes (max score=1). ⁵Measured displacement from center point (optimal score=0). ⁶Measured average distance to target with resistance (max score=0.14 m)
