There is science in all of this. Diagrams, case studies, etc... try having someone "prove" the venturi effect in more defining terms that I have used over in the many different threads that Salted and I have argued this over the years.
If someone hasn't seen the science in all of this, then they are just refusing to look.
Whether someone can detect the difference in taste between a .7"X1.25" bowl and a .97"x2.5" is objective. Sure, sure, whether someone can tell they are falling down stairs is also objective. Maybe someone can't tell... and they suffer some brain damage. Which is what I think may be going on.
Subjective would be whether the person likes or dislikes the differences. But, to say that you cannot tell that the volume and quality of smoke is different is just weird. It's like saying that you can't tell the difference between apple pie and peach pie.
