My first practice session after the PGA Show…
I set up the tees approx. 18” behind the cup, and hit putts with the sole purpose of rolling the ball to the tees.…no matter the distance of the putts (4’ - 50’).  REALLY HELPED ME gain a better understanding of distance….putts started falling in, too!  This is now one of my “GO-TO” exercises going forward.  Might help you, too…try it!
Let me know how you do!
