Combined training in session-2 exhibited significant correlation (p=8.9e-3, R2=0.6) between the exploration behavior (specificity of along the transverse axis) versus subsequent performance (average radial deviation). We defined acceleration specificity as the 95th percentile of data observed along a given axis, divided by that of the scalar acceleration. These results suggest that over-practice in the transverse axis (shoulder dominated motion) prohibits optimal learning.
