When a red flag was a misunderstanding, and the retraction posts 31–39

Nothing here should be read as an accusation against a named company, and the guidelines exist so that reports remain reports.

I keep a log of this specifically because memory is unreliable about it.

Adding the measurement that post #31 says would settle it.

Worth stating the null on red flag before we explain it: the observation may be nothing. That possibility deserves a sentence and usually does not get one.

I had read the opposite somewhere and cannot now find where, which tells me something.

I read the earlier replies on red flag twice before writing this, because I had assumed the opposite and wanted to be sure I was disagreeing with what was said rather than what I expected.

On post #31 — agreed on the reasoning, with one qualification.

A stock listing that never changes and a lead time that never varies are both worth noticing. Real operations have variation in them.

The short answer was in the first line; everything after is the working.

Picking up post #35: that is the part I would want checked first.

Evasion when asked: if a supplier does not clarify when asked specifically for method details, counter-ion form, or batch origin, that itself is a red flag worth documenting.

The right answer here may simply be that it has not been measured.

Offering a way to settle red flag rather than another opinion about it. Two measurements, taken the same way, a fortnight apart. If the difference is within the noise, the question was not answerable at this precision.

My position on red flag is current rather than settled. I have revised it once already and I expect to again, so treat it accordingly.

Worth separating two things that post #35 runs together.

Testimonials without a lot, a date, a method or a service are not evidence and are not a red flag either. They are simply not evidence.
