In the detailed instructions for optimal travel routes, you mentioned that you assume traveling by boat is 10% faster than traveling over a featureless plain overland and in order to avoid many very short trips by sea, you assume it takes 1 hour to embark on a boat (from land to sea), and 1 hour to disembark (from sea to land). I am wondering how you make these assumptions. Thank you!
