* The highest of the above Fine Offset 'Gust' values over the previous 10 minutes becomes Cumulus 'Gust'. (If Cumulus is restarting and station logging interval is 10 minutes or greater, Cumulus Latest and Cumulus Gust cannot be properly differentiated).
* The highest of the above Fine Offset 'Gust' values over the previous 10 minutes becomes Cumulus 'Gust'. (If Cumulus is restarting and station logging interval is 10 minutes or greater, Cumulus Latest and Cumulus Gust cannot be properly differentiated).
* Cumulus 'Average'  can be calculated in 3 different ways:
* Cumulus 'Average'  can be calculated in 3 different ways:
** The Fine Offset console 'Wind' value (every 48 seconds if Cumulus is running, or at every station logging interval if restarting) becomes, with default settings, Cumulus 'Average'.
** The average of the 24 2-second sensor measurements (Fine Offset console 'Wind' value) becomes, if Cumulus is running with default settings, Cumulus 'Average'. (If Cumulus is restarting, then it uses the subset of these available at the station logging interval).
** All Fine Offset 'Gust' values read over a 10 minute interval are averaged to become Cumulus 'Average' if in the ''Settings'' frame of the '''Station''' screen in the Configuration menu, you select ''Calculate 10-min wind average''.  (If Cumulus is restarting and station logging interval is 10 minutes or greater, Cumulus Latest and Cumulus Average cannot be properly differentiated).
** All Fine Offset 'Gust' values read over a 10 minute interval are averaged to become Cumulus 'Average' if in the ''Settings'' frame of the '''Station''' screen in the Configuration menu, you select ''Calculate 10-min wind average''.  (If Cumulus is restarting and station logging interval is 10 minutes or greater, Cumulus Latest and Cumulus Average cannot be properly differentiated).
** All Fine Offset 'Wind' values read over a 10 minute interval are averaged to become Cumulus 'Average' if in the ''Settings'' frame of the '''Station''' screen in the Configuration menu, you select ''Calculate 10-min wind average'' and also set the next option ''Use 'speed' for avg calculation''. (If Cumulus is restarting and station logging interval is 10 minutes or greater, Cumulus Latest and Cumulus Average cannot be properly differentiated).
** All Fine Offset 'Wind' values read (if Cumulus is running) over a 10 minute interval are averaged to become Cumulus 'Average' if in the ''Settings'' frame of the '''Station''' screen in the Configuration menu, you select ''Calculate 10-min wind average'' and also set the next option ''Use 'speed' for avg calculation''. (On restarting, dependent on station logging interval, there may not be multiple values to average).
