Error in demographic recovery as a function of number of samples. Error and credible intervals are shown as a function of the number of sampled individuals per loci for 16 independent loci. Both the error (solid line) and the HPD interval (dashed line) reduce with increasing number of sequences but both converge to a positive limit, that can only be improved on by sampling more loci. A best fitting line of the form is shown and serves only to highlight the general trend.
