I don't blame them either if people wouldn't know the difference anyways. It could possibly be 192aa for all I know as well. I by no means have had mine tested.
I've personally never experienced any typical 192aa related sides and I've never seen proof to suggest it's anything other than 191aa, so I personally just see it as speculation.
