The next time you go on the course try playing a two ball best ball scramble. Your score is pretty good. Now try a two ball worst ball scramble. For most of us, big difference. Same player, same swing, widely different results. You have a performance gap and it's not caused by your swing.
Every range is filled with players who think the answer is "in the dirt". This is an idea instilled from the day you pick up the club that to be good you have to hit more balls than anybody else. That is true...until it isn't. At some point range reps are very from tournament reps. If you don't ever embrace that concept you are not addressing your performance gap and that is the recipe to a performance plateau. Why are you here again?
If the answer is not hitting more balls then I must need to take a swing lesson to shoot better scores. It's the traditional game improvement model and it certainly has it's place as you climb the skills ladder. But if your swing is not the cause of your performance gap how is changing it going to solve your issues. In truth it can make it them even more difficult to address. The real question here is when do you stop building your car and start learning how to drive it?
It is time to SHIFT your approach and examine your game in terms of your performance gap. You will learn the on course SHIFT principles: Always Seek Neutral, AIM, and the Transfer. And You will learn how to apply them during your SHIFT practice of the Scorecard Relevant shots. This process will guide you to a better understanding of your own personal barriers to better scoring and give you a roadmap to follow on your SHIFT journey to reaching your potential.
