Brian - you have the settings on the app set to compare you to tour players. I don't know the arcoss app as well as the shot scope app. in my app, i cna toggle between tour, scratch, 5, 10, 15 and 20. I'm a 11.5 right now and want to get to be below a 10 with a real target of 5. So I normally look at my comparison to a 5 index to see what I need to do to improve. Essentially what it is telling you is that tour players would have had about 10 less putts than you had given the distance of your putts on that day. It's going to be more meaningful feedback to you though if you look at your goal index to see how you need to improve. If you don't understand strokes gained, i would suggest listening to the Hack It out Golf Podcast or The Sweet Spot Podcast. Both have episodes dedicated to the explanation of strokes gained.
