I think you two are misunderstanding each other's points. LegionZero wrote: There are multiple instances of instant copying or copying without practice. All that is needed is a theoretical capability to do it. Simply put:

-1: have i analyzed the technique completely

-2: have i got the skill to pull it off?

-3: have i got the dependancies (e.g. weapons, bombs

-4: have i got the KKG, if applicable?

So:

-Madara saw Hashirama's wood clones to the point he could tell which one was real

-Madara has the Rinnegan, so he has considerable power over chakra and jutsu

-Madara had obtained Wood Release

Therefore, he could use Wood Clones.

On the other hand:

-Sasuke saw Chidori

-Sasuke didn't know Lightning Release

-Apparently the seals for Chidori aren't there for the Lightning Release

-Sasuke couldn't copy chidori.

On the other hand:

-during the 4th war, everyone was shown the seals for Practice Brick and could use Earth Release that way, indicating that hand seals can be used for the Release part as well.

-This implies the seals used for Chidori aren't there for the elemental part, but for the shape part.
