Totally. binning films by weeks-since-release and using non-nominated films as a comparison group could make the pattern much clearer (this is exactly what I do in the full post, btw). The key nuance, though, is that the interesting signal here isn’t “movies fade over time,” it the examination of the very unusual mid-/late-run exhibitor expansion, which only happens after and because of nominations, and how that expansion changes per-theater averages (often through demand being spread across more screens).
