He walked 30 feet to get there!!! He is climbing up and down a ladder. As he is climbing up and down his distance traveled is increasing, even though he hasn't moved inch in terms of lat. and long.

At the end of his experiment the GPS said he had traveled 31 feet. It didn't say he was 31 feet from his original way point. Ooooh... that would be another way to verify what you are saying is wrong. If his results were due to inaccuracy, it would say he is 31 feet from his way-point. I bet it says he is right on top of his way-point.
