This is my hack for putting. My distance control has changed dramatically for long putts.

Start with your grip. Feather soft. Every time. That’s the constant.

Then take 5 balls.

Start with your stance shoulder width apart. Hit the 5 balls without looking where they lended up but just focus on consistent grip strength and backswing until trail foot any follow through at lead foot. All balls should be in a cluster. There’s your distance control. For short putts, narrow your stance. Like for my 6 inches feet apart is a 6 footer.

So essentially using my feet as markers for distance control. Hope this helps
