The anatomy of a question that gets answered within an hour — the long version posts 91–120

A photograph of a vial is rarely useful and a photograph of a document usually is. Redact the identifiers before you post either.

That is my reading. Someone else read the same page differently and was reasonable.

It is fine to say you cannot explain why you are asking. Nobody will press, and the technical part of the question can usually be answered without the context.

Worth checking against a second source before it gets quoted onward.

The arithmetic in post #104 is right; the assumption feeding it is the part to check.

A question about somebody else's post should be a reply to that post, not a new topic. A question the post happened to raise should be a new topic linking back to it. The difference is whether the answer is useful without the original.

That reframing is the whole thing. The facts I already had.

Quantities without units are the single commonest reason a question sits unanswered. "Two and a half" is not a dose, a volume or a concentration until you say which.

I would rather say I do not know than round it up to an answer.

Post #106 put the caveat in the right place and I want to underline it.

If your question has a deadline — a parcel in transit, a delivery you have to accept or refuse — say so. People answer differently when there is a clock on it.

This is the first time the answer has come with its own limits attached. Appreciated.

Nobody minds being asked to explain a term. The people who use them most are the quickest to define them, and a question that stops to ask is usually a question that gets a better answer.

I had written a reply contradicting post #109 and deleted it. Here is what survived.

Asking a follow-up: new topic or reply in the old one? If the answer depends on the previous post, reply. If it is a question that makes sense without the previous post, new topic. The second gets faster answers.

Confirming post #113 from a second method, which matters more than confirming it from a second person.

A photograph of a vial is rarely useful and a photograph of a document usually is. Redact the identifiers before you post either.

Written quickly, so the reasoning may be tighter than the wording.

Avoid "any advice?" at the end. It is so generic that people do not know which part of the post it refers to. Pick the specific part and ask that specific question instead.

Noting that the question and the thing people usually mean by it are different.

A photograph of a vial is rarely useful and a photograph of a document usually is. Redact the identifiers before you post either.

Post #117 is right about the mechanism and I think understates the practical bit.

Staff note on titles, since it comes up. We retitle topics fairly often, always leaving the original in the first post and always logging it. It is not a criticism of the wording — it is that a title is how somebody finds this in eighteen months.

Worth separating two things that post #117 runs together.

Post the arithmetic you already did. Half the questions here are answered by someone spotting which line of your working is wrong, and that is impossible if you only give the answer you got.

Adding thanks rather than a view. I do not have a view worth the space.
