System 3, double-extrapolated absolute errors. Absolute error of X1 for ETL, xETL and xxETL for (a) the mean, gradients 1.0 (ETL), 2.0 (xETL) and 2.3 (xxETL), and (b) the second moment, gradients 1.0 (ETL), 2.0 (xETL), 2.1 (xxETL). Results from 108 simulations. In this case, the xxETL errors do not show a clear order of accuracy, but are nonetheless smaller compared to the other methods.
