My understanding of blind submission is a few years old and may have been superseded. If it has been, I would genuinely like to know rather than keep repeating it.

Repeat testing: if you want to verify the same lot a second time, testing with a different service strengthens the conclusion. Testing with the same service verifies reproducibility but uses the same method.

Not the answer, but possibly the question that gets there.

KTurkington, post #18: Repeat testing: if you want to verify the same lot a second time, testing with a different service strengthens the conclusion. Testing with the same service verifies reproducibility but uses the same method. Not disagreeing with anyone above, just adding the bit I keep having to look up. Go to post

The claim about blind submission upthread is stronger than its source supports. I have read the source. The source says "associated with" and the post says "causes".

I had written a reply contradicting post #90 and deleted it. Here is what survived.

An observation about blind submission that I cannot explain and am posting anyway, on the principle that unexplained observations are more useful public than private.

Repeat determination on the same product line months apart is the measurement that speaks to consistency, and consistency is what most buyers actually want.

It is one reading of the data and not the only reasonable one.

Blind submission has a well-known answer and a correct answer, and the interesting work is establishing that they are the same. Nobody has done that here yet.

k.dahlberg, post #29: Worth separating two things that post #27 runs together. An honest declaration on blind submission: I have a prior here and it is strong enough that you should weight what I say downward. Stating it rather than hiding it. Go to post

Acknowledging rather than arguing. The reasoning holds as far as I can follow it.
