I think ShadyOps was talking about in the slightly uncomfortable range.
It's either comfortable, or not. No middle ground. Also, your grandmother does not determine comfort levels for the rest of the world. It is a no-brainer and it blows my mind when pilots are stingy with APU usage. The earth has been around for 5 billion years, through reoccurring ice ages, plate tectonics, meteorites, magnetic reversal of the poles, and killer meteorites, and you think the APU is going to do it in? Delusional.
