Reading through this, I agree with Tago, myself. The latest issue brought up against the usage of this seems to largely boil down to appealing to authorial intent, when that's obviously not something knowable to us under normal circumstances, so that can't be spoken of authoritatively without a degree of guesswork being involved.
The other concern which Andy brought up, that being the possibility of the graph not being literal, doesn't seem particularly strong to me, either, given that so far she hasn't outlined much of a reason for why this would be the case here, and the one example made to illustrate the point ("a lot of times manga narrations will depict imagery that is not meant to be literal but just a representation of what's going on, such as such a moon flying into the earth but the moon is depicted as almost as big as the earth") seems like something involving a lot more factors that make it immensely easier to dismiss as non-literal, compared to the case at hand, so essentially just a tailor-made hypothetical that satisfies what she describes exactly.
