what would you tell week-1 you about batch
Right, the certificate of analysis question again, but with numbers this time.
I have 4 data points over 16 weeks. The pattern is consistent enough that I do not think it is chance, and boring enough that nobody is going to screenshot it, which is usually a good sign.
The thing I would flag for anyone new: the effect I am describing showed up at week 51, not week 5. People give up long before the interesting part.
Interested in whether this matches other people's logs or whether I am an outlier.
best — the order this archive was captured in
Three years on this site and the questions have not changed at all. Which is depressing or reassuring depending on the day.
Strongly agree. Mass% and area% are answering different questions on the same document.
purity and net content are two different numbers, same vial
Disagree but this is the good kind of wrong — it is specific enough to be checked.
redact your own name, not the vendor's batch details
Strongly agree. Mass% and area% are answering different questions on the same document.
You have restated the marketing copy. What is the actual substance here.
Removed a chain here. The rule is one line long and it is not negotiable.
the batch number or it did not happen
Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.

This is the correct framing. The COA structure matters as much as the number.

Slight fix: the number was 99.3, not 93.7. Decimal point, but a fairly consequential one.

Adding to this: water content is doing more work than the comment implies.
Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.
What is the method line say? Not the technique, the actual method.

No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.
Cosigning. The batch number is load-bearing information.

Strongly agree.
Yes, exactly this, and it is the bit that took me 78 weeks to accept.

What were the related substances listed individually?
Four months on the site and I was confusing area% and mass% in every post I made. One explainer thread and it clicked.
