Instead of focusing on the formation. Look through them; use your peripheral to keep them in the frame. That way if they move left, right, or rotate you will notice that they are doing it and be able to compensate. It sounds as though you are concentrating to hard on them and loosing sight of were they are on the ground, until you look at you vid and see that you were following them. --------------------------------------------------------
Some one must go to the edge for others to be able to find it. But if you go be sure you can make it back.
