NBU Schedules - Override / preference

Just checking this in relation to NBU 7603 and any changes which may have crept in........

If I have a standard schedule setup within a policy of say a daily INCR (Mon-Thur, Sat, Sun), weekly FULL (Friday) and Monthly FULL (Friday) - do I still need to exclude the Friday's on which the monthly and Weekly clash from the Weekly schedule or will the Monthly automatically override the Weekly if it has a longer retention period ?
