Open ground makes the world of difference, i am not overly sheltered here, the wind was coming from the west mostly, this
meant it came straight down between a row of houses and a row of bungalows, prob close to 100m between the rows and
not a great deal in the way, but what is in the way would have impeded the speed for sure, i am prob in a better than average
position for wind in a semi urban environment
With your setups being in open land, would there have been that much difference if they were at 10m opposed the the 3m?
