because in the worst case the films may have lost 1/3 stop in speed, but certainly not more because of the refridegeration.
If they were frozen then 98% no loss of sensitivity, but you can always bracket for your first batch.
That is a nice find. I’m still dearly hanging on to about 4 rolls in the freezer.
