How do you know that the double oven controls to 1 degree? Where is this 1 degree measured? I'm sure it holds the thermistor to 1 degree, but the 10811 is a large object that might have its own temperature gradients. How do you know that the outer oven does not produce gradients that reduce the gain of the inner oven? How much does the 10811 internal oven current vary vs ambient?
