What they are doing with methylphenidate (Concerta in this case) is linking the established onset and duration of the drug effect (12 hours) with corresponding BE AUC intervals across the 12 hour period. As far as I know they generally stick with the usual 80-125 intervals. Perhaps in Europe, in general, there is more flexibility on occasions for the intervals?
