Shaza - the whole thing has been made unnecessarily complicated by the EU authorities. The safest thing for you is to "follow your company procedures" as they should have been approved by your regulatory authority. If those 'procedures' are not clear, ask for a ruling from your Training department. They should have issued you with guidance on how to apply the 'new' minima where they appear. If you cannot get an answer, adding 50 is safe, of course.
