im using GA to deal with raining data, and so confused on the rule to choose the better model


Rule1
in the book, it said you need choose a model to FIT your semivariogram points


Rule2
in the HELP CENTER, it said smaller Root-Mean-Square , nearest between Root-Mean-Square and Average Standard Error , and
make Root-Mean-Square standardized equal to 1



BUT i got 2 different model results under these 2 rule

Result1 , the model seems very close to the semivariogram trend , but its Statistical property is not obey Rule2
