When I grid the same data in Surfer 7 and again in a newer version of Surfer using Kriging, my results are different

Different results are expected between Surfer 7 and Surfer 15 when gridding with the Kriging algorithm. This is due to improvements made to the Kriging algorithm between Surfer 7 and Surfer 8 (and henceforth in all subsequent versions of Surfer). It was modified to improve the accuracy and to eliminate some errors that occurred in Surfer 7.
