I think that we are trying to say that for the general purpose of a weather station there is absolutely no need to do gust readings at 1 second intervals.
Some time ago when I started with the WeatherDuino system, I did several experiments to try to determine what should be, or what could be the best interval to do wind gust readings.
Interestingly, I remenber that doing gust readings at intervals of 1 second always produced lower readings (also produced more flat graphics) than when the readings are done at intervals of 2 to 3 seconds.
Anyway, as Alan said, one thing is the "transmission" time another one is the "measurement" time. In the case of WeatherDuino, both are 3 seconds.

Yes, I understood and I know standards WMO.
I have a VP2 to standards WMO http://www.infoclimat.fr/observations-me...ghlight=05

The relief at home is particular with winds which come from the valley by going up (it is very particular on the left with 100m or on the right there is more this phenomenon.
If you look at the comparative one on MéteoCaldas, you will see that the direction of the winds at home is often different.
I simply seek to understand this phenomenon at home.
