1. proportional
2. as high as it can be without too much condensation dripping on the eggs

1. X2
2. 99%. You can tilt the egg boxes VEEEERY slightly to one side to let any condensation buildup roll down the sides of the containers instead of dripping on the eggs. I use a shim made out of a little piece of cardboard.
3. I've heard anywhere from 88-89 degrees.
