I would say it helps with skill/ patience/ discipline because there is a lot of players, myself included at one point time who would or will swing at every pitch in which case you would rarely ever walk unless it was a intentional pass, so with the quick counts having started off with a 3-0 count will give the player more incentive to hold up on a pitch to try and draw a walk causing the player to look and follow the pitches more and be able to identify pitches better, hence becoming a better batter. For me It was a struggle to stop myself from swinging at every pitch I literally had to start putting the down the controller and start watching the pitches movements before I started to be more a discipline hitter.
