No problem here it is I'm not done with experimenting on this quite yet @zalive. You say you still don't understand how some can say the racket is slowing down. Well believe it or not I still can. I think it all depends on your point of reference. It's all about the distance from the axis to the center of mass and where you add the weight. The period is dependent on two things the distance from the axis to the center of mass and the inertia (aka Recoil Weight.) You're saying the racket is whipper because you probably have a loose grip and whip the head through the ball because the distance from the COM to the axis is much shorter than is you had a tight grip.
