Try this:
Make an effort to start in your PCA in order to more regularly stay in your PCA. Emphasis upon "start."
Upon setting up in your initial position, be it L, C, or T, manually, subtlely, and briefly raise your arms so that they each point down the approximate line of the left and right borders of your PCA. Then say to yourself, "I've got this area right here." When setting up as C, say to yourself, "I've got the action on this side of the court." In other words, once you've established for yourself the area that is your primary, it's easier to focus on that area while remaining aware of where the ball is outside of your PCA as necessary.
The problem many may have (and me, too, until doing this every time) is that they initially set up with their eye on the ball outside their PCA, then never get a chance to determine the approximate borders of their PCA. They start outside their area and never get themselves back in. They start out ill-focused, and keep that ill-focus throughout whatever play develops thereupon. They get caught up in the game and never draw their focus into their PCA until something happens there, and then it's often to late to observe a play develop or see what's been happening that demands attention.
Do this not only when the ball changes ends, but upon each rotation also.
Stay in your PCA by visually establishing for yourself your PCA upon setting up on every play.
Might be overly simple, a bit ridiculous or it might not work for others. But it works for me. And, as always, I'd be interested in any critique to this method that may come along in response.
