Figure A4.

The computational effort required to reach a fixed uncertainty threshold depends sharply on $\Delta t$. The total computational effort is determined by the total number of trajectories sampled in that condition (i.e.,${\sum }_{i=1}^N{M}_i$), multiplied by the length of each trajectory. Note that the curves are not monotonic, since the number of required trajectories increases superlinearly with $\Delta t$, but the number of timesteps in each trajectory decreases linearly with $\Delta t$.
