Wow, this is a whole lot of churn just to sort out what goes into your grocery-getter.
There is a dirty little aspect no one mentions here (because they may not be aware?) The formulation 'meets the spec', yippee. Pop open the bubbly. Does the batch in the bottle meet it? Are you buying from a company that plays the 'test until you get a pass, then put that on the CofA' game? What are their data handling guidelines for replicate results that are outside of acceptable test precision limits?
Since no one I know of gives you batch data unless you buy in bulk, you may be buying a pig in a poke.
