Not at all silly when you consider the temps at altitude. On average decrease, 10 (C) per 1000 feet.
I'm not trying to play 'gotcha' but -50 is not a very big margin when the OAT (ambient air temp) is -40. The freeze point of Jet-A (used in airliners) is only three or so degrees higher. *note at ~ -40 degrees, Celsius and Fahrenheit are equal*
