I have seen my husband help others by putting an elevated rest on their bow. I had a recurve that we could not tune. My husband has a way of tillering bows by tracing the limbs over top of each other to check for the lines. He gets longbows to shoot perfect, but on this Darton the lines were way off and the arrow nock wanted to go a half inch higher than normal. Instead of re-tillering the bow or having the arrow sit pointing down, he added a Pararest and it worked. He found that the typical, he calls, porpoising when people shoot three under with the nock raised up, with the added elevated rest can shoot with a more level arrow and eliminates the porpoising affect. I shot that Darton with the higher arrow nocking point and Pararest, three under for a while and we did not need to move the nocking point, as long as I did not draw too hard with my ring finger.
