Perception of hands in space

[streak]

Would appreciate some elaboration of how, from the player's point of view during the swing, the hands should be perceived as they approach and continue through impact. Primarily swinging, hitting also.

For a long time (prior to TGM), for me a go-to simple swing concept has been "make a smooth circle with the hands". Not literally, but an image that helps me keep my mind in my hands and on my effective rhythm. It still is, but with some TGM learning I am beginning to improve my understanding and implementation of this notion. I am improving the frequency of my more effective rhythm and my PP#3 accepting and sustaining lag pressure, and where I may best perceive my hands should be to optimize my sequence. Backstroke and transition seem to be fine, through impact is still a work in progress.

A specific concern: approaching impact, the hands have a "down" component to their travel .... when does this component start to change to "up"? Thanks.
