I agree anyone who has actually mowed a lawn optimizes for the least turns. E.g go all around the edges at the start and finish by doing the rest with as few turns as possible. Which is also how the vacuum robot does it because the edges are finicky with it bumping around the rest is easy. It is more efficient to turn less for a human at least.
