What is the difference between the 2 wind spike control methods?

Do I also need to set something in CumulusMX perhaps?

I have the 6410 Davis Anemometer.

Normally, enabling one of the WeatherDuino anti-spike routines is enough to avoid occasional wind gust spikes, however defining it also on Cumulus doesn't cause any problem (10m/s is a good value, I think).

With WeatherDuino, using Method 2 for spike control is preferable than Method 1.
Method 2 acts more like a progressive filter. The greater the last gust was, the greater the current gust can pass the filter.

Method 1 only acts if the current gust reading is greater than 13.8m/s and it may introduce some errors on the gust readings if the wind gusts are constantly above that value. Method 1 will be removed on the next software versions.

I saw the graphs on your web page, and indeed especially on the last day, there is a value that seems a spike. Was it thunderstorm when those spikes happened? I ask this because I already saw thunderstorm causing very strange wind spikes. I will keep a eye in your webpage, and try to see if the spikes continue to happen and in what conditions.

How could you qualify your location, regarding to winds: Very windy, windy, or occasionally windy?
This can be important, because the WeatherDuino can detect very quick bursts of wind (1 second)

I have the 6410 Davis Anemometer.

I'm supposing you have configured the TX software to use it.
