Using your lead arm's position at address and partway back as reference points builds a repeatable menu of swing lengths mapped to specific carry distances.

How to perform it
1.Pick two or three lead-arm 'clock' positions for the backswing, such as 9, 10 and 11 o'clock relative to address as 12.
2.Hit shots from each position with the same tempo and follow-through length every time.
3.Note the carry distance each position produces with a given wedge.
4.Build a simple personal chart of clock position to yardage for each wedge in your bag.
What you should learn
•A repeatable, measurable reference for partial swings instead of guessing at 'feel'.
•How consistent tempo, not just swing length, controls distance.
After a few weeks of practice
You'll have a reliable personal yardage system for partial wedge shots, and long/short misses on approach and layup shots become much rarer.
