General Credits
First, a huge thanks to IgorI! Working with inexperienced problemsetters over a 10 hour timezone difference is already difficult enough. But due to a wide range of problems with the round, the preparation process took several months. I personally have nothing but admiration for his patience and commitment throughout the entire time. He worked closely with each one of us to prepare every problem, helping us rewrite statements and redo tests over and over again to make sure they were as good as possible. He hasn't been included in this table, otherwise he would appear under every box.

Polygon Commits
The stats here may be a bit misleading, as many of the commits made were very minor changes (fixing typos in statements, etc.)
