All system-performance point estimators are corrupted by sampling error for random experiments of stochastic systems. We are interested in simple useful methods of reporting meaningful digits of point estimators. Based on three criteria-loss of statistical information, number of characters required, and likelihood of user misinterpretation, we advocate our procedure for use when reporting many point estimators in tabular form. The procedure discards meaningless digits of the point estimator, and all but the left-most non-zero digit of the standard error. These two resulting values are separated by the "@" sign.
