I focus on getting my arrows into the kill zone consistantly rather than obsessing over grouping, getting a second shot is rare in a real world hunting situation. I use a foam deer instead of a block or bag for better visualization, it really improved my shooting. Recently I had a slight problem with focusing on my target spot(I shoot instinctive with a recurve), so I drilled a small hole in the middle of a Daisy Shatter Blast target disc and toothpicked it on the spot I wanted to hit. The bright orange disc sharpened my focus instantly and is a lot of fun to shatter, great confidence booster too.
