Humans are so much more impressive than most can ever imagine. At 12 I witnessed a guy at a basketball camp get brought in to shoot 1 handed, shooting from the free throw. Surprisingly he worked his way up to half court, not missing a single shot. The guy easily shot over 10 from half court with one hand. The guy was at least 60. In my opinion the sensitivity that is required to be absurdly consistent at whatever you want is possible and doable, but sometimes not obvious and takes effort to figure out how to get to that point for you
