I seem to be maintaining the view of the cue-ball instead of, say, the center of the cue-ball's path to the object ball. Except for stretch shots I can stand the same distance from the cue-ball while surveying every shot.

It would make more sense if I maintained perspective on a point more towards the center of the shot's action, wouldn't it? It works for me maintaining a perspective on the cue-ball. I suppose it could work equally well for other people using perspectives - object ball, cue-ball path's midpoint, etc. I think the important thing is to maintain perspective on something throughout the movement so your brain has something to tie the two images together.
