This note proposes a simple procedure for reducing the variance of estimators of equivalent parameters by using a weighted combination of soil measurements. The weights for these sums reflect both the redundancy of information in closely spaced observations, and the differing influence of regions of the soil profile due to nonuniformly imposed loads.
