In this case study, let's take a look at the influence that the impact sweet spot has on the energy data tile within the Capto software.


This player came to me a couple days ago complaining about struggling with distance control, primarily on long lag putts. She said that there would be times where she'd hit her first long putt in a round and it would be really short, so the next lag putt she had she'd try to hit a little bit harder and all of a sudden it would go way long. Ultimately she didn't know what to work on. She was lost. She didn't know if there was an issue with acceleration and how much speed she was trying to hit the ball with, or if it was an issue with her green reading process.



The first thing I wanted to do was to use Capto, and this is one of my favorite pieces to the Capto software because it measures how much torque is being applied to the putter head at the moment of impact. What we saw very quickly was that the first putt she hit had an energy loss of 22% out of the toe, meaning the face was opening, or twisting at about 450 degrees per second (see image below).


So what does that mean? Well, this was about a 40 foot putt so this ball could have gone 20% further than it did, so that's about 8 feet further than it actually did. After this putt came up short, she hit another one and this time she tried to hit a little bit harder than the first one. A perfectly natural adjustment to try to make, however, this putt only had an energy loss of 6% out of a heel, meaning this putt was struck closer to the true sweet spot of the putter and as a result the ball went way long.


"I don't know why that's happening!" She said. "That's exactly what's happening when I play."


Assessment Putts: Putt 1 & Putt 2


The nice thing about Capto is we are able to measure this, and answer this question! We're able to see that where she thought the sweet spot of the putter was versus where the sweet spot of the putter actually is, were totally different.


We had put some face tape on the putter and she hit these putts and we saw that this first one hit wasn't hit that far out of the toe in actuallity, but rather a little closer to what would be considered the middle of the putter, maybe about a centimeter or two towards the toe.


Just as a side note the sweet spot of a putter is almost never on that sight line, and that's because of a lot of different factors. The type of hossil or shaft, or the length of the shaft, the size of the grip, and one of the biggest influences is how much pressure or how tightly the player is holding on to the putter as well.


So for her we actually found that when she tried to hit it close to the heel about half an inch more towards the heel, maybe a little bit less than that, was when she actually started to get less energy loss. So we got to 1.7% heel and a total energy loss of 1.3% and what we did was we drew a dot on the putter as a reference to where she needed to be trying to hit the ball.


She started to line it up more out of the heel and she started to gain more control over the distance that the balls were rolling because we now eliminated one of the variables. Originally, she didn't know if there was an issue with how hard she was hitting it, and she never actually considered impact location. And so now that she knew where she was hitting it on the putter face, it was much easier for her to guage speed because she was able to dial in how much or how hard she needed to hit it to get to go a certain distance whereas before she was guessing blindly. She'd hit it and it might have been the perfect speed to get it to go the right distance, but when you're hitting it and losing 22% out of the toe and that ball is going 20% shorter than it should, you're going to end up hitting the next one harder, and what happens if you hit it towards the heel like she did. Well now it goes way long.


This is one of the many added benefits to the Capto Putting software is being able to look at this impact sweet spot. Make sure if you're using this feature in Capto if a player is struggling with distance control. It's really going to make a big difference in a player's ability to control distances. If you're inconsistent in where you're hitting the ball in the face you're gonna be inconsistent in the distance the ball is going to go and you're going to find yourself three or four putting far too frequently. It's a great addition or it's a great tool within the Capto software that I would highly recommend utilizing frequently.
