It's not that you aren't shooting instinctive, you still are. It's that you have removed a portion of awareness of your subconscious. You have remove sight, I have no idea where my arrow is when I shoot, but my subconscious sure does.
I have shot a LOT at night, with very little light, even shot a nice 8 pointer on a recovery on late night. The guy with the tracking dog was holding a little pen light, before LEDs existed, and this was his reply....
"I've seen it ALL now. I thought this was just going to be some kind of goose chase but I have never seen anything like that. I had now clue you could shoot one of them bows like that in the dark. If I hadn't of heard about you killing that night hog a few years back I'd have thought you just gotten lucky back then, but two for two ain't just luck."
A few years after that I killed a charging hog at night with 5 witnesses. All those were shots were with gun metal colored shafts.
That reminds me, I need to try something in total darkness. Maybe I'll do it after this latest Ice Age of the "climate change" like what happened int TX a couple of years back.
