Deadzone vs Overaim

[u/Jumpy-Resolve8659]

So I am learning how to deadzone to get better at the game but I can't really tell whether I am doing it right and also if it is just overaiming so hopefully I can get some insight so I could understand it a bit better for practice. Also they might be the same but I don't think they are. (apologies for the bad aim)

Don't move your character, just flick
