Now, whenever I get a new bow or arrows. The fist thing I do is put a piece of blue painters tape at the bottom of my target. I shoot 2 arrows at 10,15,20,25,30,35,40,45,and 50 yards, by floating my tip over the blue tape. At this point I make a mental note of how high my impact point is. From here I figure out where the majority of the arrows fall into a 4-6" group. So for the C&N its 10-30 or so yards. say thats 20", and that will put the arrows on or +/- 2-3" of the 11 ring. I will now from here on out, hold a gap of 20" for every shot in those ranges. And after a little bit of shooting there is no thinking involved its just natural for the bow arm to go where it needs to go. I never fully rely on my gap, as I phase it out. But I feel it helps me with adjusting to every new bow.
Now at any 3D i go to or hunting situation, I know my secondary point is around mid shin on a deer, 3-4 " to the right. This allows my 100% confidence and zero second guessing. Sorry if that was clear as mud, but explaining it does not come easy to me.
