| Good point, PaulT. Percieved not actual being the key to the issue in my book. A deviation of say 1/2mm when the ring is close to the bow may mean an error of 30cm at the target face. Whereas, 1/2 mm when the ring is furthest away you can get is much much less of an error, say 2 inches. Making the furthest away position more accurate. (And it encourages you to try to hold the bow more steady?) |
