someone tell me if this is right
the sharingan can copy jutsu and analyze basic chakra flow of the opponent in order to perform that jutsu
because if this is true, i dont think the sharingan can copy gentle fist, it can certainly help one mimic the motions but when it comes down to the chakra control and precision necesary for one to insert your chakra into specific chakra points and disable them the sharingan doesnt have enough insight for that
that said the sharingan would analyze that chakra is being pushed of the palms/finger tips and probably be able to copy that but,so they could do arbitrary damage to the opponents chakra system, but attempting gentle fist would be like a fork trying to have the same precision as chop sticks, they can both do the same thing essentially but you need much better control and practice to use chop sticks
