I think a lot of Sakura supporters are forgetting     a little something about Byakugan. Specifically the part where it says The Byakugan is also able to more effectively follow high-speed movements to better react to them. Which means that Hinata can track fast-moving things within her field of vision - which happens to be 20km. For comparison, Neji's maximum range by the time of his death was 800m, or 0.8km.
