I didn't go quite that far down the rabbit hole, but considered similar. Essentially my dark current at -10 degrees is 1e or less at any exposure time I am likely to ever use so I considered that good enough for all practical purposes. Really my master darks are more read noise characterisation than dark current. Maybe I should just calibrate with a master bias instead.

The only difference there of course is hot pixels, but with a good number of subs APP will probably reject those anyway.
