The weighted mean of relative standard errors for mean volume, basal area and stems per ha as a function of plot radius (maximum radius for relascope plots). The number of plots is based on a budget of 420 min for one cluster. Assumed costs (Equation 3) are LT = 15, BT = 0.7, TT = 0.7 and ST = 7.0 min. The optimal number of plots for a cluster using the optimal plot type and size (marked with an arrow) is 18
