Humans have no instincts, as biologists define the term, at least. Everything is either a reflex or a learned behavior. Point shooters miss the A a lot, under stress, at 5 yds plus, if you don't let them cheat by lining up their bodies on the target, prior to the start signal, and vary the height of the targets, as if on a hill side or a staircase, perhaps?. either that, or they are not faster than the sight using shooters. Under 10ft, tho, realistic fighting distances, point shooting works just fine, to get A zone hits, faster than sighted fire.
