Agreed. Anything claiming to be a "wizard" for Kriging really needs to
be a psychic wizard that can read your thoughts and understand your
data. A better device would be an "Interrogator":

*ping* Your data seems to be discrete small integers, are you sure you
want to model it as a Gaussian? [*yes*/no]

*ping* So you want to model your data with Gaussian cofactor response
p-value thresholds from an underlying Bayesian surface? [*yes*/no]

*ping* That last question was nonsense. You're just clicking "yes"
until you get a surface model - any surface model - right? [*yes*/no]

*ping* okay, at least you are honest. I'm deleting the kriging module
now, go find a statistician.
