It’s more so the fact that your mind is good at noticing patterns. This is why archers that start out don’t have target panic, but it always develops later on down the line. Once you shoot 1000 arrows your mind eventually says “when I see target I must hit button to release arrow”, because you’ve repeated the pattern over and over. It gets to a point where before you can even consciously settle your aim, your subconscious mind sees the target and instantly tells your fingers to press the release button. It’s at this point you have to find a way around your subconscious mind, and that’s why surprise releases are used.
