"Second - and here is what is novel, at least to me - is that there's a bonus structure in the game designed to award bonuses for when you have accomplished tasks. The first bonus award that I'm awarding myself looks at constructing a walk so that you make an orbit around the biggest possible chunk of territory; that is to say, repeated walks along the same path will get you zero bonus, but going out of your way on a detour will add to your score, and trekking through unfamiliar territory in a big loop is the best."
