No one knows except the people who say them. When you hear one of these gems, ask why they believe that.
Some people love the sound of their own voice.
Seriously, advice given should always be taken with careful consideration. For instance, A diver that has spent 99% of his diving life in one particular site may have more insight into what may be the best practice for that site vs a well seasoned diver visiting the same site for the first time.
So how would these points be passed to a new diver? I will research something in a heartbeat, and also have the education and experience to differentiate an authoritative source. Most new divers don't know this.
I was actually chastised for not moving out because I was just standing there -- mentalling going through my self checks! and I was told I 'worry too much'.
