100 meters: Accuracy of the original GPS system, which was subject to
accuracy degradation under the government-imposed Selective Availability
(SA) program.
15 meters: Typical GPS position accuracy without SA.
3-5 meters: Typical differential GPS (DGPS) position accuracy.
< 3 meters: Typical WAAS position accuracy.

Cache
first off aside from what the others do with the manual Garmin averaging, I
prefer to let my little Magellan sit for atleast a minute then let the units
self averaging do its thing for another minute, this has been the norm for
our over 25 caches I have only had to adjust the coords once, but that was
due to interference....
besides if the coords took you to zero everytime what fun would the 04/04/04
and Graldrichs caches be?
I agree with the 15 foot radius, that is pretty much the GPS norm.
as the Event cache and the ZERO experiment goes even the same units will be
off a little..
as far as cache plundering goes...
someone was curious to what was going on as they spotted a cacher caching.
this someone was greedy
someone found it by mistake and was greedy..
