But then again, I'm a new diver so I may be missing something

There is at least one training agency (obviously not PADI, SDI, or SSI) whose standards dictate that any dive below 100' must use Helium. Their thinking is that the risk of getting narked is too great past 100' without Helium in your mix. Obviously, there are divers who think the same way, or there wouldn't be an agency with those standards.
 
I'm sort of glad we don't have SCUBA police. I try to look at all the rules and policies of certification agencies like I look at the advice of consultants. I am the person responsible for my own dive safety, I welcome all the consulting advice I can gather, and then I make my own decisions.
 
I said borderline, not straight dangerous.
 
Nitrox is made and checked with a certain margin of error, so "32" can mean anything from 30.5 to 34 (in my experience). And at 34 your max is already 103 ft. Then there is the error of your depth gage, etc. So if we trust the tables, I'd say "borderline".

Your contention would be true of every depth with every mix of nitrox. Every mix of nitrox has an MOD, so your contention would be true of every depth from 20 feet (for pure O2) on down, not just 100 feet.

Do you seriously just dive it as whatever they tell you it is despite it analyzing as something else? If the analyzer says 34%, I'm not gonna pretend it's 32 and dive it as if it were 32.....
