Mean Wind Before and After start
Before the start (when the countdown is not zero) the d10 builds up an average based
on the readings taken each time you press the circle button. By capturing the mean
wind repeatedly you’ll build up a better idea of what the average wind direction is.
Mean Wind After start
After the start the mean wind is reset based on the current heading and the tacking
angle - no averaging is performed.
