While this sounds impressive, the mismatch between the highest resolutions for this long simulation is $\\mathcal{O}(10^{-1})$. Meanwhile, the mismatch between resolutions for the more typical simulations tends to be $\\mathcal{O}(10^{-4})$, despite the resolutions being similar to the long simulations'.
