a Evolution of the root mean square error (RMSE) averaged for each run. The first column represents the RMSE for session one divided in shoulder (top) and elbow (bottom), while the second column depicts the error for session two. The black lines represent the calculated linear regression for each combination of subject, muscle and session. b Evolution of the PRff for each subject. The black line represents averaged PRff across subjects and its corresponding standard error. The first column represents the PRff for session one divided in shoulder (top) and elbow (bottom), while the second column depicts the value corresponding for session 2
