I think the questions raised here are valid, but this is a poor choice of a place to raise them. You really have no idea of the poster’s breadth of knowledge and background.
You wouldn’t trust a doctor over the internet to diagnose your rash, tumor or whatever – you would want to make sure of their credentials, check their experience, etc.
When it’s this important a subject, I think you need to have confidence that you know who your ‘opinion givers’ are.
Good Luck and a Gut Yahr !
