== What do the various wind speeds in Cumulus correspond to, with Davis stations? ==
Davis
* The latest Davis 3-second average is treated by Cumulus as 'Latest' (available via <#wlatest>)
* The highest of the station's 3-second readings over the previous 10 (configerable by adding ''AvgSpeedMinutes=N'' in [[Cumulus.ini#Section:_Station]] where 'N' is number of) minutes becomes the Cumulus 'Gust (available via <#wgust>)
* The Davis 10-minute average is the Cumulus 'Average' (available via <#wspeed>).
Note that if you sample these readings at shorter (real time) intervals it is possible for Cumulus 'Latest' to be lower than Cumulus 'Average' because approximately half of the 3-second wind speeds will be higher and half of them lower than the 10-minute average.
If the Cumulus figure seems lower than the Davis figure see [[#My_Davis_station_shows_a_higher_maximum_wind_speed_than_Cumulus]].
