A computer-implemented method for fitting a medical implant to a recipient, the medical implant being operative to stimulate a physiological system of the recipient over a plurality of stimulation channels. The method includes: determining, based on measurements, an initial stimulation profile for the plurality of stimulation channels； determining a representative stimulus level of the initial stimulation profile； determining a fitting stimulation profile by modifying the shape a shape of the initial stimulation based on the representative stimulus level profile； and configuring the medical implant according to the fitting stimulation profile.
