Dont want to speculate and am using feats which are facts as a basis.As of now we got no feats in battle from Hinata except getting soloed by both Pain and Neji for the former neg diff.Thats all
Even in the movie all she does is give her chakra to Naruto instead of actually giving a fight
Everything else is fanfiction
No, you're not. You're trying to make a big deal out of Hinata's one second of hesitation as if it actually means anything. 64 palms requires the user to have fluid foot work and hand work, precise aim and reflexes, and fast movements altogether so as to prevent the opponent from having any chance of escaping the 64 palms combo. Hence why it's said to be unavoidable, as the opponent can not escape it after the first hit lands. the fact that the Juubi clone was unable to escape the manevour despite Hinata's hesitation shows how insignificant and meaningless that moment was in regards to her skills with the technique.
And hinata does have feats, not much, but they are there; enough to know and conclude logically that she is above part 1 Neji.
