Boxplots of the $K=2000$ ABC posterior precision utility values for the range parameter ($\{{\widehat{u}}_{LF}({\mathbf{z}}^{(k)},\mathit{\xi })=1/{\widehat{\text{Var}}}_{\mathit{\xi }}(\mathit{\lambda }|{\mathbf{z}}^{(k)});k=1,\dots ,K\}$) for all designs when using the importance weight update method with the ABC posterior displayed in Fig. 3 (solid line) as input prior. The design (station) numbers correspond to the numbers in Fig. 1
