The measurement of recipient-specific operating parameters for each of a plurality of stimulation channels of a stimulating medical device. Generally, a recipient-specific operating parameter is measured for selected stimulation channels. These measured values are then used to estimate the same operating parameter for the remaining stimulation channels. For each such remaining stimulation channel, the accuracy of the estimated operating parameter value is determined, resulting in the estimated operating parameter value being deemed either valid or invalid. The validated values are retained while in invalidated values are replaced with a directly-measured or re-estimated operating parameter value.
