How critical is sensor temperature when calibrating?

I like to cool my 533 to -10°C - it's not too hard on my battery and I'm not sure if, at my level, I'd notice any real difference in noise going any lower. I've built a library of dark frames at this temperature and noticed some were coming in -9.8°C, -10.2°C, so out of OCD and how easy they are to do, binned anything that wasn't -10°C on the dot. 

My gut says this slight temperature difference is not too much of an issue, if any. I'm naturally reluctant to delete an otherwise good sub just because it's 0.1c different in temperature to another, but it did make me think and to ask this question - how critical is sensor temperature when adding your calibration frames to a stack?

I really wouldn't worry about 0.1 or even 0.2 degrees difference.

Ditto.
