It's all about THERMAL MASS, the more thermal mass you have, the harder it is for outside variables to drive the incubator off temp.
Better to use a large egg box than a small one. The Barker's used to use entire trash cans for one clutch, with a couple feet of perlite. That is a LOT of thermal mass, and that box stays steadier, at temp, than some little deli cup of perlite that will change temp if you breathe at it, ya dig?
The water bottles add great thermal mass, but they are also an immediate source of perfect temperature water that can be added to the egg box if needed. You don't want to add 73F tap water to an egg box that is 89F, you are going to significantly affect your incubator temperature. Using water that is already stored inside, at perfect temp, avoids that swing.
