OP -- what is it you think you should know that you weren't taught?
In my PADI EAN class, I teach a "30 second Nitrox class" which, in my opinion, teaches a student what they need to know to use Nitrox.
a. Always analyze your own tank.
b. Only use 32%.
c. Stay above 100 feet.
d. Breathe.
And I can "teach" that in about 30 seconds. OK, what else does a recreational diver need to know?
But, back to your critique -- How does "improper filling" of a tank increase the risk of DCS? Perhaps you are overthinking the question?
I (unfortunately) teach the "computer only" PADI class -- but I also give my students the formulas to calculate MOD and EAD and have them work the problems. I have no idea why others won't/don't do this.
I booked on a local SSI NITROX course run by my LDS before reading this thread. Mind you, I guess the only way to get Nitrox fills is to get the card. And Nitrox diving is really popular here.
But seriously. $400 for a theory book that took 5 mins to read and comprehend, a plastic dive table and 2 Nitrox dives is not exactly good value.
Will I use Nitrox in future? Still not convinced benefits outweigh risks.

Sorry for digging out this old thread.. I recently took the EANx course as well. And I was really surprised that the material has changed so much since 06 when a friend shared with me his materials for knowledge..
I was pretty disappointed that the dive tables were no longer included as well, although the instructor was really good and actually taught me the formulas to calculate EAD and all ..
The only thing lacking was the oxygen exposure tracking on the DSAT table (which my instructor taught me to use as well).. any idea where I can get the DSAT EAD/O2 exposure table?
