Waypoint Averaging Information for Outdoor Handhelds
Waypoint averaging helps to achieve the most accurate position possible for a waypoint by refining its location through short-term averaging or multi-sample averaging.
Short-term averaging is averaging the waypoint one time for only a few minutes. The averaging of the waypoint should be done for minimum of 5 minutes, but 7 to 10 minutes is preferred. After giving the unit this time to average the location you can then save the waypoint. If present, the sample confidence percentage bar can be ignored for the short-term method as it is used for multi-sample averaging.
Multi-sampling averaging involves taking multiple short-term samples using the waypoint averaging feature. This has proven to be the more accurate method of averaging a location or waypoint. If the device has a sample confidence bar each sample should be allowed to run until the confidence is 100%. Some devices will keep track of the number of samples completed, it is recommended to get between 4 to 8 samples taken at least 90 minutes apart. Each sample will reflect a Distance Adjusted based on the previous sample, each of these will contribute to a more accurate reading.
