A quote from a very good hitting coach "Additionally coaches that MAKE you stand in the front of the batters box are not very smart in my opinion as that changes your timing and rhythm and if the pitcher has a fast ball and can change speeds they own the hitter….that is a 7 foot adjustment and that affects timing! You have tried to create a data base or sometimes I term it a swing DNA so you can react to the ball and your brain recalls the approximate speed, recognizes spin or movement and tells your body and hands be here or there and hit the ball.
