One of my team's mentors actually spent nearly two hours going over this equation. I personally find it somewhat pointless: nobody is going to be using the quadratic when they're in the middle of a competition. At the end of his lecture, the mentor finally came to the same conclusion several of us had already made two hours previous: ideally, you want half of the boxes in your zone to be in a stack (or all of your boxes in two equal stacks).
