I think that most people waste the time between games. It's a good time to make adjustments. Take a pad of paper and write 1 or 2 things that worked and 1 or 2 things that didn't work in the last 2 games. You might find that the adjustments come more naturally during points without you having to force yourself to think about them.
The ball and opponent should be the in-point focus, the rest is pre-point background.
