I got a Bryton 35 last wk, and if I stop for length of time, we are talking less than 8 mins as far as I know, for some reason it completely loses altitude. gps track is spot on though.
That sounds about right, all devices should be funny about altitude as they use barometric altitude sensors. I'm not sure how the Garmin behaves, but even they give some rather crappy altitude readings (there's a completely flat Cat 4 on Strava in my village created by a Garmin). There are no good GPS units on altitude due to the way the technology works, even the best handheld hiking ones need very regular calibration at a known height.
