I have been diving NITROX for almost a year now with roughly 30 dives on Nitrox. I have the 'NITROX' recognition card, not the 'NITROX DIVER' card (the difference being one has 'diver' on it the other doesn't). Nobody has ever refused me a fill nor use of a Nitrox tank while on vacation.
I discussed the difference with my instructor at the time and chose the recognition class (it was still winter), and this class actually taught us the physics/math which another class (not NAUI) I looked at only taught the use of a computer.
As far as planning the dive goes we learned what to do in class (MOD @ 1.4 PO2 with contingency of 1.6 PO2 or variations thereof). Be sure to watch your O2 clock for repetitive dives. If you arrive on site and the depth exceeds these numbers then you either abort the dive, have a hard bottom, or go back and change gas.
It works for me.
