There is no specific definition of distances for short game and a good rule is: from the distance of a full Pitching Wedge to the green. Therefore it differs from person to person (for example 60–110meters).
For distance control we use different lofts on our wedges. PW, GAP, SW, LW and can also uses different sizes of the swing to control it.
All swings has to be done in a repeated and controlled tempo so you after some practice know how long the ball will carry and from there it gets easier to score well.
Doppler radars with Statistic and good presentation can be of big help here. This is Target training. "Direction and Distance" Today even smaller and less expensive ones will help a lot.
