Since bicyclists do not want their average speed to be diminished when they come to a stop, the computer will only record and average when the wind is blowing.  It stops recording below approximately 1 mph.  That means that  if the wind blows for 2 hours at 20 mph and 2 hours at zero, the average shown will be 20, not 10!  Please keep this in mind for your desired use of the Vortex. 
if you want to know the real average wind speed - even with spells near zero, do the following:  reset the computer, note the time.  When desired, simply divide the total number of wind "miles" on the display by the number of hours since reset.
