if you want to prove "instinctive" go out on a pitch black night and shoot at a lit candle at 25 yards
that will tell you right there if you're shooting pure instinctive or if you use a sighting method
funny you mention this. I shoot in evenings alot on the weekends. And I try to squeeze all the daylight I can out of my shooting. At the edge of dark, where I cannot see where I am hitting, I all the sudden start grouping great, but alway high. So actually, mental gap shooting is probably messing me up. Its hard not to notice the fuzzy vision gap.
