Graham and Ashkahn have been around the proverbial float block. They've visited centers all over the world, consulted with them, and trained them on how to make their centers as good as possible. It's tempting to ask them, specifically, what are some of the most common mistakes they've seen in this time. 

Fortunately, someone did. The duo hash out exactly what they think of when it comes to both "common" and "expensive" construction mistakes for float centers, especially where those two points intersect on the float center Venn diagram of unhappiness.
