Zero bearing

"Note that the 'bearing zero when calm' setting only affects 'instantaneous' wind direction (i.e. the value read from the station). The average bearing (i.e calculated by Cumulus over a period) will always be zero when the wind is calm, because it takes speed into account."

The result is that at the end of the day I have "average bearing" that is not true.
Is my question right?

I don't know, because I don't understand the question. As far as I am aware, Cumulus calculates the average bearing correctly, taking into account the wind speeds.
