Uncle Pug:Dung recognition doesn't necessarily mean one is a snob.
Confidence isn't being a snob, either. Yo're reaching a point where you recognize the stuff you've PROVEN in the water isn't always what is being professed out there - by some agencies, publications, instructors and (gad...) posters on SB.
Big-T probably nailed the motivation for the "Pro Diving" tip you mentioned... but to you it was a big "duh..." I think that's pretty swell.
Continue to prove the stuff you're being told, and the stuff you're reading, and apply the fecal filter.
