Posting this under the heading it deserves: Mean kinetic temperature explained without the mathematics Everything below is what sits behind that.
Two things I would like separated before anyone answers on mean kinetic temperature, because they get bundled and then argued about as one thing.
The first is descriptive: what has actually been observed, by whom, and how. The second is causal: why. I am asking about the first only.
On the opening post — agreed on the reasoning, with one qualification.
Light protection is easy and cheap. The original carton exists for a reason and a vial stored in it is protected without anybody having to think about it again.
Temperature excursions in transit are common and are not all equal. A few hours warm is a different event from three days warm, and neither is visible in the vial on arrival.
