If an archer is consciously adjusting any reference in relationship to the target even though they may be focusing only on the target, they are not truly aiming totally Instinctively.
If an archer is aiming by consciously adjusting a gap within their periphial vision in relationship to the target even when there focusing 100% on the target...it's Gap Shooting.
It usually occurs with archers, who start out in the beginning by being very aware of their gaps and through repetition and time...less and less conscious effort needs to be placed on analizing the gap and it NEARLY becomes instinctive.
This is exactly how I aim the majority of the time.
When I aim totally Instinctively it's when I'm shooting very fast or when I'm shooting aerial targets. The techinique primarily relies on using proprioception, muscle memory and the sight picture subconsciously to adjust the aim while I consciously focus on only the target.
Gap Shooting and Instinctive Aiming can be very much alike. The ONLY difference that they have between them...is what the archer is or is not consciously aware of while they are aiming.
Just remember...it's not a sin to do either one
