A very crude model of the chemistry involved, would have two components
involved. A constant, due to background radiation etc, which would be
independent of temperature, ant a thermal component, which would approximately
double for every 10 degree C rise in temperature. This model would give a worst
case scenario of a fourfold increase in ageing speed, as a result of replacing
Freezing at approximately -20 by fridge storage at 2-3 degrees C.
There are so many questionable assumption in this model, that its probably
quite close to taking a tarot reading.
I do know enough chemistry to justify the last sentence above, but not enough
to stand behind the first paragraph.

I have a lot of older film stock that is literally irreplaceable like
Agfapan APX100 in pretty much all major formats.
I've kept all my monochrome film (I shoot color only digitally) in the
freezer with good results. But circumstances have forced me to displace
that from the freezer into the fridge.
Any thoughts on lifetime of this film at the fridge temps (40F is common,
whereas freezers tend to be set at 0F).
