I think there is another piece of fine print in that area. I'm not sure
where I saw it, probably one of the Garmin docs.
The idea is that you can't trust the first few seconds of data when it
switches from not-enough satellites to enough. I've seen it give bogus
position (way off) marked as valid. I think they all happened right after
recovering from not-enough-satellites.
I'll scan log files if anybody wants examples.
