You'll probably be ok, but something to keep in mind is that home refrigerator/freezers don't hold a constant temp. You might have read -13 at that point, but they can potentially cycle by quite a large range. 10 degrees is not uncommon, and some swing even more. The ideal under those circumstances would be to use a logging thermometer to find out what the highest temperature the freezer gets up to, and then use the recommended length of time for that temperature.

Yeah one of these days I'll get a quality thermometer. To be honest though, I checked the freezer quite a few times throughout the day before I put any cigars in and nearly every time it read -13C. Could have been great timing haha

Even at -10 though, a little room for fluctuation, I still give it another 24hrs.
