If you dont know the secrets of something, how can you copy it? How can I make a functional replica of a computer if I don't know how it works? I can't, lol.

Concerning the Sharingan, the page says it can't copy a technique if it can't see the user forming the hand signs for it. While that it canon to my knowledge, a lot about the Sharingan is insane honestly imo. We know it can perfectly ratio chakra for techniques, seen when Sasuke altered the ratio of chakra when he combined Amaterasu with Naruto's technique. Not sure why it technically wouldn't be able to copy Naruto's technique despite all the things it can do, but oh well. I'm glad there are limits to its abilities, as it can already do so much as it is.
