Naruto deflecting 5 bijuu at once was him only using KCM, not spsm or six paths chakra.This was even before he aquited KSM...and was only starting cooperating with Kurama.

But to be fair, they did state that Naruto was intentionally dragging himself away from the kids and letting delta take advantage.
