The premise of this thread attempts to use Naruto and Sasuke supposedly moving the moon to reverse scale to Hagoromo since he provided said power (and did the feat himself although with no concrete timeframe), which would scale to others. However..
Now that I've gone back and read the chapter, the moon wasn't moved at all. We know Hagoromo and Hamura
created and moved the moon, but chibaku tensei doesn't automatically involve movement. Nagato's multiple CTs did not move from the origin of the black gravity spheres, nor did Sasuke's. Madara's CTs didn't move until he specifically motioned for them to start traveling.
However with Naruto and Sasuke, the moo doesn't move from the center of origi . The only movement visual clues are from the cast being reverse summoned. Makes sense, since they were
only given the power to create the moo. This is also provable by the
anime .
So there's no timeframe to be used here.
