This is freakin’ AWESOME! I had been using a calculation of military speed from one of Leslie Alcock’s books to figure travel time for my characters, but this is so much easier (and works out about the same). Plus, it’s fun! Thank you so much for sharing it!
No problem! I was doing the same thing 🙂
