alright, lets say there is a hypnotic factor with the genjetsu, why waste chakra on it. For intance let say kakashi and gai are playing rock, paper, scissors. Kakashi would use the sharingan and predict that gia would throw rock. Now Kakashi can do two things, he can either throw rock as well and piss gai off, or throw paper and beat guy. Whats being suggested with the hypnosis is that kakashi will predict rock, hynotize gai into throwing rock, and then Kakashi would do his thing. It seems like the hypnosis step is a waste of chakra if you can predict the attack.

and if Naruto elites are all about chakra conservation, Kakashi wouldn't waste his time hypnotizing gia if he could already predict the attack... hence why i still believe there is an inconsitancy in regard to kakashi's level 3 and sasuke's level 3.
