Call it instinctive, memory conditioning ,muscle memory through repetitive practice, ETC. or what ever, it still amazes me how the brain goes into auto pilot when the shot presents itself. No thinking, no gauging distance, no thought of holding higher or lower, it just happens, and ZAP!, youve made meat.
All the sights and gadgets in the world will ever replace the amazing ability of the finest computer out there, the human brain. Through practice, and repetition you develop hand eye coordination, that cant be compared or equaled.
Even though it takes hrs. of practice and shooting, in a hunting situation does it get any better than traditional archery, using the finest computer ever devised? I think not.
Call it what you will, but its hard to beat.
