Looking at the GPX file, it missed quite a few trackpoints. If you look at the timestamp there should be a new trackpoint about every 10 minutes. But in a number cases there is a gap of 20 minutes, and in a few other rare cases there is a gap of 30 minutes. One example of a 30 minute gap was on 1/14 from 5:11 GMT to 5:41 GMT. But, like you, I think it works great and missing a trackpoint from time to time isn't much of an issue, as long as the OK / Help / 911 messages are more reliable (which they are, due to the methods which they are repeated).
