Summary:The limitations of the sampling constant principle as a quantitative measure of sample heterogeneity have been examined. Computer simulations have been used to determine the sampling constant from the lateral variations of intensities. Important deviations arise with respect to the precision as well as the accuracy. The computer simulations have been shown to be a valuable tool for performing error analysis, by application to real intensity data from inclusions. The simulations yield results which confirm seemingly discrepant experimental observations. [A.J.B.]
