That’s better , as Mikee says the movement on that video is after the shot. That’s proven by the path of the white after the shot. In previous videos that movement is probably happening during the shot.
Our of curiosity are you deliberately trying to have more of a stun follow through with the white ? If your aiming for a topspin shot then I would aim higher on the cue ball to impart more topspin . You won’t need to hit the cue ball so hard .
