An electrical neuromodulation system and method of meeting a therapeutic goal for a patient using a neuromodulation device. A modulation parameter value is varied by a step size. The neurostimulation device instructs the neuromodulation device to deliver electrical energy to at least one electrode in accordance with the varied modulation parameter value. A therapeutic feedback indicator is compared to a threshold in response to the delivery of the electrical energy. Whether the therapeutic goal has been met is determined based on the comparison, and the previous steps are repeated to determine the modulation parameter value at the resolution of the step size that minimizes energy consumption of the neuromodulation device required to meet the therapeutic goal when delivering the electrical energy to the electrode(s) in accordance with the varied modulation parameter value.
