I'm getting to it, but what I'm saying is that the amount of damage a character can take seems to change depending on the plot, making it harder to get an accurate measurement of how much damage characters can take before they run out of Aura.

Jaune who is said to have a large amount of Aura gets beat up a lot and has been in the red twice from pretty weak hits, while Weiss who has studied almost all her life (according to her) can't take a single hit without being taken out. This would imply Weiss has a weak Aura, but if it is true that Semblance is fueled by Aura (a common theory going around) then how is she able to spam her Semblance as much as she does. Like I said, characters are as weak or as strong as the plot demands.
