Error in demographic recovery as a function of number of loci. The error (on log-log scale) reduces linearly as the number of loci increases (solid line). Using 4 times the number of loci halves the error. Likewise, the 95% HPD interval also reduces linearly on a log-log scale with increasing loci (dashed line), and also appears to reduce by a factor of 2 with a quadrupling of the number of loci.
