Follow-up: The most useful thing you learned here that was not the answer you came for

On the subject in the title: The most useful thing you learned here that was not the answer you came for Working notes rather than a conclusion.

A digression I have been saving for the right category.

It is not useful and it is not a question. It is the kind of observation that would derail a technical topic and is perfectly at home here.

Analytics first, in my case, and I still find the practice category the harder read. Chromatography has one right answer more often than logistics does.

On balance I think that is right, and I would not bet much on it.

Lounge question, no agenda: does anyone else keep a physical notebook for this rather than a file? Mine is more use than anything I have typed, and I cannot entirely explain why.

Adding a source would improve this post and I do not have one to hand.

The Lounge is also where to say the obvious thing you have been holding back in case it was too obvious. It usually is not, and two other people were holding it back as well.

Something I have wondered without ever asking: is there a good reason the vocabulary in this field is so inconsistent between suppliers? Half the disagreements here start as terminology.
