Well we had a good sun break today here in central washington, so I took my bow out back and shot a bit. I was hitting the mark right on or keeping them within 2 inches at 18 yards while standing. But for some reason when I sat down to shoot I was missing by a foot, low and to the left. I haven't shot for a couple of weeks, but before it didn't make any difference if I was standing or sitting, I hit the same then. I like to practice sitting & kneeling, as I hunt from the ground. I hate to end a practice session feeling bad, so I finally just shot standing and did well.
