Greg,

Attached are graphs of your data.  gregd.all.png shows all of the
data, and gregd.peak.png is the highest distance deviation of 369
meters, which is less than the default 500 meter threshold.

It looks like there is a diurnal pattern to the data with increased
deviations around midnight local time (the X axis times are UTC).

It also looks like your home elevation must be about 380 meters since
the altitude variable drops down to negative that amount frequently,
which would occur when that value is taken as zero (there is a special
case in the code to treat some values as zero).

I tried overlaying my data and yours, but there seems to be no
correlation between the peaks in my data and the peaks in yours.
Interestingly, my data does not show a similar diurnal pattern.
