In the final round of The Masters, Rory McIlroy missed several shorter putts on the right hand side of the cup.

If he didn’t notice it, you can be sure his putting coach would have seen it.
It’s valuable information to help improve Rory’s putting stroke, especially under pressure.

If you miss a 5 – 10 foot, flat putt, is there a consistent side you miss?

Are you showing improvement with this drill, week after week? Is there a side of the hole that has become your common miss?
Is it aim? If it’s the right side, is your Putter face open at impact?

Your practice is an opportunity to “perform”. Create skills challenges. Keep track of your performance.
Remember, on the golf course, your aim is important.
So, it is important to focus on your aim with every shot you hit during practice.
