Process recipe evaluation method, storage medium, assisting device for process recipe evaluation, and liquid processing apparatus

A method for evaluating a process recipe used in a liquid processing apparatus that performs a liquid processing by supplying a processing liquid from a nozzle to a substrate while rotating a holding part horizontally holding the substrate about a vertical axis, includes: storing the process recipe in a first storage part, which includes time-series data of a first combination of parameter values including a position of the nozzle and a rotation speed of the substrate; reading the process recipe from the first storage part; reading a pre-prepared risk data from a second storage part, which is determined by associating a second combination of parameter values with a risk information corresponding to a liquid splash risk; and displaying an assisting data for the first combination of parameter values in the process recipe, based on the process recipe and the pre-prepared risk data read from the first and second storage parts.
