Hmmm. Anyone know why this happened? under recent extremes for today it has the same wind reading as yesterdays extremes. But on the speedometer its showing the correct numbers.
It's not clear to me why you think there's a problem. It's quite possible that your average wind speed did reach 8.3 mph at 12:40, but did not have that value at the time the log entries at 12:40 and 12:41 were made. Do you have Cumulus calculating the average wind speed, or the station? From the way the figures change, I would guess the station.
