Behavior of rearrangement distance estimators on 100 simulations from a permutation of n = 1,000 elements evolved by inversions using (A) a pseudouniform model, and (B) a uniform model, with initial breakage probabilities drawn from a flat Dirichlet distribution. The real number k of inversions is on the x-axis, and the estimated number of inversions $\hat{k}$, according to several methods, is on the y-axis. It emphasizes that pseudouniform and uniform models are very different.
