thanks Dr for doing this on the HM device.i have one also and still trying to correlate what device signals to me to what my shot pattern/trajectory results are. so many ways to create short game shots, and not only the wrists but body torso turn is important, if I dont turn my body with shots usually get more lead wrist extension, almost a scooping ,but much less extension with body turn. seems like the HM graphs give more info than the pictures, and I think the goal is to decrease as much as possible the impact sudden loss of flexion with less of a sharp valley in the graph x axis, if I am understanding correctly?.
