Yeah...I had a friend who was a pistol instructor (passed away some years ago) who started his lessons with a blank piece of paper as a target. I believe that the exercise was to train the shooter to focus on the front sight as opposed to something like a bull that was downrange.
It works. It is a good exercise for anyone shooting irons.
