It’s data they should have had to begin with, they made the claim. Of course it’s going to be questioned, they could have been upfront with the data.
What other reason would they omit it? Other than to mislead if it wasn’t actually 100%.
It’s funny how I am “demanding” something that would be just basic decency to include along with their claim, they provided the data for the sound after all……
I am saying every single one of these claims have never wound up being actually true since they go against the very nature of physics. Yet people perpetuate the claims and defend them without the supporting data.
So to not provide the data for one claim, while providing the data for another is only done to mislead from the truth.
Sorry for not accepting what they say at face value since it goes against multiple things.
