I have to scream the same thing that Yoda stated! You must strike the ball with the pressure points. #1 drives (direct drive), #3 recieves (indirect drive).
You can't get lost in the subtle difference between 10-3-A and 10-3-B, until you really feel the lag pressure. The body will do amazing things and will make subtle changes without any concious thought.

How often would you think of the position of your wrist, elbow, or knee when asked to throw a ball to first base? Your body simply creates pressure against the back side of the ball in the most efficient manner that it had done before.
