I recently noticed that the length of commercial diver course in NYD is 72 days and not 16 weeks:

Dane2427 from the forum in the link did the course in august 2014, Maybe there is somebody here who did the course in March and can tell me what is the exact course lenght?
I sent mail to NYD few days ago but didnt got answer yet.
