This phenomenon can be explained by Weber's law, which states that the just noticeable difference (JND) between two stimuli is proportional to the magnitude of the stimuli. In this case, the JND for Jonathan is higher when there are 200 cupcakes compared to when there are 20 cupcakes. This means that it takes a larger difference in the number of cupcakes for Jonathan to notice a change in the former scenario.
