Flying40, that's something that I feel qualified to answer, and that sure doesn't happen often on this board! I do a lot of fast shooting on large/close targets (Cowboy). I can tell you exactly what I see during a string.
I see the sights, however I'm focused on the target. The sights are a rapidly moving blur. However, they stop moving the moment they are where I am looking at the target. That's the moment the shot fires. I can not tell you when I pulled the trigger, or even that I did. The gun just goes off. Then everything is a blur again until the instant that the shot fires on the next target. For that one instant, everything is clear.
When shooting with a target focus like this it's easy to miss your target (whether it's the whole target or just the A zone). I find that when I miss, it's because my eyes missed the spot on the target that I want to hit and I didn't stop the shot and let it happen. Most of the time I can pull the gun back to target, but not always.
You shoot where you look. If you aren't looking at the right spot on the target, you're just not going to hit it.
Does that help to answer your question? I don't know if it did or not, but it was the best I can do.
