The standard on the sensory Duo-Trio Test will be updated, along with all of the other standards on forced choice discrimination test methods, to make the Thurstonian delta the primary measure of the magnitude of a sensory difference, with the proportion discriminators, P(d), from the guessing model becoming a secondary metric. Other technical and editorial changes will be made as needed.
