Don't get me wrong, as I'm not in any complete disagreement, but didn't you test as a CWI to become a CWI( I remember it was quite an ordeal for me, it was several hours worth of questions and hands on, then sweating for over eight weeks before finding out the results)?, therefore you didn't obtain the transistion completely without any testing whatsoever. I think the LIII is correct if there were "never" any testing and a cert was issued in that regard.
more of your thoughts and discussion are welcomed,
