I’m 11 months in with Arccos and I’m pretty happy. I previously used golf shot and 18 birdies. I have the link so I rarely have issues missing shots. I find that when I listen to what the data is telling me I tend to pick the right club. For example after using it a few months I looked at the data and saw that for my 7,8,9 irons I was literally never long and was short more than I was on the green. Started clubbing up and I started hitting more greens. Same with the left vs right off the green. It’s helpful to me. I was an 18.7 indeed 12 months ago and now I’m a 16.8. If my driver wasn’t so wild it would be better.
