I think it gives hitters something else to think about. Bill is correct in saying that the load occurs when the pitcher moves forward. I’ve played games against pitchers with good velocity that would vary their load times each pitch. Almost like a baseball pitcher in the stretch varying the knee lift with a slide step. They would rock back and hold for 1,2,3 and even 4 second counts. Then explode forward. It messed my hitters up lol. I told them to start calling time out if she holds more than two seconds. All JMO!
