Ah, interesting! Does that "two weeks" of exposure mean two weeks total of cold exposure? Two weeks after cold exposure? Or something in between?

I'm only a moderate caver, so the longest I've been exposed to cold in that context is something like 16hrs straight, or maybe 32hrs total in a 3-4 day period; most of my exposure caving is much less than that, more like a few hours at a time spaced apart by at least a week.
