Of course you know what they're doing. You're a professional instructor, and your way is superior to all. But unless you've done a lot of research on how the brain functions when it comes to learning and performing complicated tasks, I highly doubt your explanation of what we are doing when we are playing "in the zone" is going to be accurate or correct.
Anyway, different pros do different things. James Aranas just looks at where the cb needs to be, then lines up behind it and sends it to where it needs to go.
Here's a great drill where it's pretty easy to see his straightforward approach. Plus when I played him I watched his stroke and his eye movement very closely. The kid looks straight through the cb at a distant target, ghostball more than likely, and then he steps into that line that sends the cb there and shoots. Gerda Hofstetter described the same approach to Allison Fisher, where she talked about seeing the shot line and then dialing into it, and when she feels like she's dead on it she shoots the shot.
