This may be a silly question...

To my untrained eye, in the kinematic sequence chart of an elite golfer (link to graph below), the pelvis, thorax, and arm are all slowing down in rotational speed before/at impact - it makes me wonder if the rotational speed of the club could be increased further if they were all peaking at the same time right before/at impact? Or in reality, do the muscles in the human body somehow fire better (faster) as a result of sequencing/peaking in that particular order?

In the kinematic sequence, why is it that the pelvis,
