Both AVG and ¢TMP can be viewed with WPT, but they cannot be used in
a route. (To use either waypoint in a route, they must first be copied to
another name; refer to Renaming Waypoints.) AVG and ¢TMP will be
overwritten the next time averaging is done.
Once an average is computed, you can clear the AVG waypoint by pressing
CLEAR.

Data Collection Guidelines
Your results and differential accuracy will vary depending on the baseline,
satellite geometry, number of satellites, and angles of these satellites.
We recommend the following guidelines to help ensure a successful data
collection session.
For Centimeter Accuracy:
5 sats with elevation > 15° : 25 minutes + 3.0 minutes/km of baseline
6 sats with elevation > 15° : 22 minutes + 2.5 minutes/km of baseline
7 sats with elevation > 15° : 20 minutes + 2.0 minutes/km of baseline
While collecting data:
1500 CM credits + 180 credits/km of baseline
(May require more time to collect if there are gaps or relatively low
elevation angles, and if the raw data sample rate is set to 2 or 3
seconds.)
When collecting for centimeter accuracy, the quality indicators
don't increment for the first 2 minutes of a session.
For Submeter Accuracy:
4 sats with elevation > 15° : 15 minutes + 1.7 minutes/km of baseline
5 sats with elevation > 15° : 12 minutes + 1.5 minutes/km of baseline
6 sats with elevation > 15° : 11 minutes + 1.2 minutes/km of baseline
7 sats with elevation > 15° : 10 minutes + 1.0 minutes/km of baseline
While collecting data:
800 CM credits + 100 credits/km of baseline
