Smith:

Of course you have credibility. Maybe not a lot of tact, but credibility, yeah.

All I'm saying is that your trip was a lot longer than most people's hikes, and that since most people don't have that much time to devote to their trip, they'll have to achieve a higher mile-per-day average than you did.

This isn't meant in any way to criticize you or how you hiked; I'm merely pointing out that most folks are limited to 24 to 27 weeks and need to keep this in mind.
