I agree with your recommendation.

But I was also trying to gain support on "which axis value should I choose for my variable" and your answer does not help :-).

I have rather little basis for making the choice of the end time for representing an accumulated quantity but, at least, CF does not forbid it. I guess I have to seek agreement inside my scientific community and that it is not CF's role to decide upon that.

Are there people interested in taking the discussion further? We seek the answer to the question: "In which cases would another choice (other than mid-point) be relevant?".
