My response =
WHO CARES?
I will be testing a few things going forward but won't be posting anything on this forum about them...just tying up some loose ends.
Too much effort is involved in arguing with people who have it all figured out. I have the mechanical/scientific knowledge to argue some points...but it would be a waste of time....I have other things to do. I don't test for you...I test for myself.
My advice? Go find a cone filter and sit on it? Wear your engineer's boots when you do....
