Cost-plus-loss as a function of plot radius (m) with weight of 0.08 each for RMSE of G, N and V in the loss function in two subsample tree selection strategies (S1 = fixed, S2 = relascope) for fixed-radius (a), relascope (b) and concentric (c) plots. The optimal plot size (minimum CPL assuming fixed plot number) with each plot type is marked with an arrow
