A linearized least-squares method for calculation of the corrosion parameters is described. Predicted errors are compared with numerical simulations. These errors are compared with those from the 3-point method and the BETACRUNCH method. Programmed in Turbo Pascal on a personal computer, the procedure, including error calculation, is executed in several seconds.
