Does the removal of the lid significantly increase the cooking time?
The removal of the lid doesnt affect the cooking time to any significant degree. Why? Filing only takes 5 seconds and if you keep the lid horizontal and move it about 8 from center exposing the pan so you can fill it, you actually dont lose much heat, if you look at the dome thermometer. The unit recovers temperature quickly. I think of it this way. Take a pan of water put it on a stove burner, bring the temperature of the water to 180 degrees, remove the pan from the burner for 10 seconds and see how much the temperature drops. My guess is not very much, the same is happening with the food you are cooking which is 70% water.
