*yawn* I'm bored about talking about this.The Hamura Chakra all of you are talking about IS Hinata's Normal Chakra she's always been using.
The Film didn't really fully explain the connections between the Hyuga and Hamura bloodline very well
But Hinata did have a vision, (so you can assume there is some connection)
Even Hanabi has some Hamura chakra inside her it's not exclusive to just Hinata.
Hamura chakra is basically Hyuga clan chakra. Don't get it mixed up
If you don't believe, then just wait till February.
The main point is that, Hinata doesn't really change Strength wise.
She's still weak and a Damsel in distress for about 70% of the film
