Post #147 describes the usual case. This is about the unusual one.

The cost of a submission is worth stating. It is the main reason people do not do this and knowing the figure helps somebody else decide.

j.castellanos, post #109: Recording a reorder result against the original is one of the highest-value contributions here, because consistency over time is what a single result cannot show. Worth saying I have only my own numbers here, and n is small. Go to post

Adding the measurement that post #151 says would settle it.

A difference inside method repeatability is not a disagreement. Saying so in your own report prevents somebody else reading it as one.

The claim is narrower than it sounds, and deliberately so.

Date the submission as well as the result. Turnaround is part of what people want to know and it disappears if only one date is recorded.

I have said this before in a thread nobody could find, so it is worth repeating.

This topic was closed 45 days after the last reply. Closing is automatic for quiet topics so that a settled answer does not collect new questions underneath it. If you have a follow-up, open a new topic and link back to this one — that keeps both readable and gives your question its own title.

Moved from Regulatory by t.vasquez. Category placement is not obvious from outside and getting it wrong is expected. This topic will get better answers here. The move is recorded in the public log citing R7.
