Around the green, most amateurs use one swing length and just "hit it softer" for short shots by decelerating through impact. That's exactly backwards, and it's why so many chips get chunked or bladed.
The better method: match backswing length to distance, and accelerate through every single shot, even the tiny ones. A three-inch backswing with a confident release goes further than an eight-inch backswing you're trying to slow down mid-swing.
Shorter swing, same tempo, always finishing through the shot — not decelerating into it.
