I have done many things athletic my entire life. I have played baseball into my adult years in a men's league. The thing I have noticed is that when I am playing well, whether it is fielding a ground ball or swinging at a pitch, it is like the action is in slow motion. When things are not going well, I realize that I am not even aware of the ball from about 10 feet in. I just react to where the ball last was and it's path of motion.
I have noticed the same thing in my golf swing. Sometimes it is fine, but sometimes I am not even aware of the downswing. It just seems to happen so quickly that I have no control over it. This may one of the reasons that I can shoot 73 one round and 93 the next. I have been aware of this problem for some time, but have never heard it mentioned until I read the term "downswing blackout" in another post in this forum.
I would be interested in others comments and/or personal experiences on this plus drills, solutions etc.
