As far as I know, that drift is quite normal. If you leave GPS
receiver in one place, there always will be some drift. It depends on
chipset used in GPS. For example SiRF III has greater drift than
older, less sensitive chipsets.
More important is precision while moving and the same SiRF III based
receivers are much better than older receivers. That drift doesn't
occur when moving. Also more important is keeping signal, and again,
SiRF III rarely loose signal, even in bad conditions.
I don't know what chipset is used in FR, but I wouldn't worry about
