5. The method of claim 1 , further comprising forecasting third data, wherein the third data are data indicating an estimated ability to hear with the prosthesis if temporally spaced aural training tasks are executed in the future with different temporal spacing between the tasks relative to that which was the case for temporally spaced aural training tasks temporally linked to respective temporally spaced aural tests of the plurality of temporally spaced aural tests.
1. A method of forecasting subjective efficacy of a hearing prosthesis implanted in a recipient, comprising: subjecting a recipient to a plurality of temporally spaced aural tests, the aural tests evoking hearing percepts with the hearing prosthesis; obtaining first data indicative of the recipient's ability to hear with the hearing prosthesis based on performance by the recipient of the temporally spaced aural tests; and forecasting second data based on the first data, wherein the second data are indicative of the recipient's ability to hear with the hearing prosthesis at one or more temporal locations in the future.
