For some reason, I can't get ArcGIS to work on Chrome, so I can't comment inline like I'd want to -- so I'll just put my comments here.
You Five Keiths system cracked me up. The photos are so good! Alison and Yuanziyi's comments about the non-100 scale percentages make sense -- but I didn't think about/notice it because I'm so bad at math. To attempt to quantify your experience along every stop is (by necessity) very complicated... It's certainly a great idea, if only a starting point.
The tool is absolutely perfect for your project. You've fitted it to your purpose nicely. One question I've had, though, in going on this "virtual journey" with you, is what your own motivations were for undertaking the pilgrimage. It's clear it was more often than not a grueling, frustrating experience -- so why did you do it? What kept you going? Maybe you mentioned this in your previous iteration, so forgive me if I missed that -- but given the personal emphasis you've adopted with the second iteration (and which is working quite well), I can't help but wonder at this exclusion.
