You'd be surprised.
Way "back in the day" NAUI required students to do a CESA from 60ft.
Personally I think that doing it from 45ft with your air turned off and no LP hose is a great idea. It would appear to be a good simulation of being out of air and actually having to do a CESA.
Remember, the best way to train for something is to make it as real as possible.
Chris--I was under the impression that while NAUI has minimum standards, you are allowed to exceed them?
Edit: Remember--an instructor who is with students doing a CESA should always be WITH the student on the ascent, no more than an arm's reach away. This way if the student has a problem the instructor can help them, AND to make sure that the student is not breath-holding--ie, direct control. In this situation (45ft no air no LP hose), you should be able to reach your tank valve anyway (you should be able to reach your tank valve!) If the instructor is doing their job correctly, you should have two possible places to get air--the instructor and being able to turn on your tank valve. Also, if this were a true CESA you might still be able to get occasional small breaths off of your regulator, as the air inside the hoses also expands upon ascent--a great reason to leave it in your mouth during a CESA.
