Welcome to the world of EASA but, to be fair, you will get a different interpretation of CARs from each provincial office of TC as well. Each competent authority in EASA is allowed to "interpret" the rules even though they are supposed to be standard. Indeed, the UK CAA have been known to apply a rule because "that was what was in the mind of the person that wrote the rule" even though the law is supposed to be read in plain words and actually says something quite different! On being asked for clarification, it turned out that the guy was dead anyway. Go figure.
As far as theoretical knowledge goes, you will get a reduction in training hours for your CPL - our training manual says 400 hours.
