Figure 6.

Variance in cycle completion time $\langle \delta {\tau }^2\rangle$ plotted against the number N of sites per cycle by keeping the entropy $\sigma$ per cycle and the diffusion coefficient D constant for $N\ge 3$, while the velocity $v\left(N\right)$ results from Equation (24). We show $\langle \delta {\tau }^2\rangle$ for three different choices of $\sigma$.
