[Discussion] cold chain is doing more work than we give it credit for
Right, the data logger question again, but with numbers this time.
I have 2 data points over 32 weeks. The pattern is consistent enough that I do not think it is chance, and boring enough that nobody is going to screenshot it, which is usually a good sign.
The thing I would flag for anyone new: the effect I am describing showed up at week 17, not week 66. People give up long before the interesting part.
Interested in whether this matches other people's logs or whether I am an outlier.

lane reports need origin, destination, carrier, and actual transit days
Not convinced. The evidence does not support that reading.
Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.
Strongly agree. Peak temperature is not the whole story.
the Netherlands to the Netherlands: 16 days with GL Biochem and 6 days with MKM. Same route, different carriers, variance is real.
time-at-temperature integral is the dose, not just peak temperature

Sceptical. If this were true we would see it reflected in the data and we do not.
The gel pack lasted 22 hours in a courier van, then liquid. Powder itself fine, the cold chain mostly died in transit.

This is the "correlation is mechanism" thing again. You changed three variables at once.
data logger is the standard, gut feeling is not
