If you shoot field - or want to - it’s good to get into the habit of practicing estimating distance. This is easy to incorporate into a daily routine, especially if you can measure what your normal walking pace is. When out and about, just take a few seconds to estimate how far away a lamppost or other object is, and then pace it out to see how close you are. After a while, you may be surprised just how accurately you can do this. Terrain and other tricks played by the course setters may still throw you, but you will rapidly improve your scores this way.
Paper tuning for barebows is often a good idea too, especially as a final check to make sure everything is singing. If you get the paper tears in opposite directions (as in the left column) then when shooting long and short shots your have to adjust your aim or your face reference in opposite directions, which is difficult to remember. You may have to make multiple small adjustments to centreshot, spring tension, or possibly point weight to get it closer to the right hand column.
