Uncertainty behaviour for the different methods for grid-based simulations. The runtime, which is used here, is always the theoretical runtime from Sect. 4.2 normalised to its maximum value in the respective figure. Here the large shear interval is normalised to a theoretical runtime of 13.2 × 10⁶ and the small shear interval to 14.4 × 10⁶, respectively. Solid lines show fits to the data described in Sect. 6.3. The left and right panels differ by the used shear interval, which is indicated in each column title.
