The main focus of this paper is an investigation of the effect which the accuracy of data representation may have on the results obtained by using standard peaks-over-threshold (POT) methods. It is shown that this effect may lead to a substantial shift in the resulting predictions of long return period extreme values for specific types of estimators combined with the POT method. A brief discussion of the implication for the estimation of confidence intervals on the various estimates will also be given.
