Since you can play this game with two people, should we include a co-op% category?

I estimate it saves 30-45 seconds to have a player 2 pommy. Well practiced could maybe save a little bit more. Personal opinion it should just be a variable on all the boards to minimize clutter, but then co-op any% would show up higher than single player any% with a run played 30 seconds worse. I personally am fine with that, but could see how others may not be fine with that.
