Data Adaptive Planning determines the expected utility of a
single new measurement using existing data and a data descriptive model. The method can be used for experimental planning. It is
applied to scaling laws for magnetic fusion devices. Explicitly, the scaling of the stellarator W7-AS is examined for a subset of data. In control parameter space regions of high utility are identified and serve for fixing discharge and machine
parameters for upcoming discharges. It will be shown that a skillful analysis of experimental uncertainties is of utmost importance for significant results.
