Paper is definitely needed and required. I just find that too much is not helpful. It’s trying to find the right amount. I found this is especially true for archery. I had my bow right next to my back door and would try to shoot a 5 shot group every day at 40 yards, the max I could do in my backyard. This was in the months before archery deer season. 5 shots at 40 every day or close to every day was very helpful. If I did more, I didn’t see any benefit. When I would go to the archery range and shot the 3D course, it felt like it was very helpful and I found I could keep going and didn’t make sloppy errors because it felt a little more interesting not just shooting at small foam dots. If I could shoot paper every day and no other targets, I would, but not a ton just a small amount.
