When Chipping or Pitching there are a number of targets. The first is where are you aiming to land the ball.
You want the knowledge to understand how much run out each shot type will have.
And of course, your final target is the hole.

Of course you should measure the end result. How many short pitch or chip shots do you leave dead,
or even sink? But for the most improvement, on each shot, aim at a spot on the green and aim to land the ball there,
becoming an expert at how much the ball will then roll-out.
