WD wind gusts are low compared to WeatherLink

I did have the IP data logger set to disconnect every minute in WD, to allow an update to weatherlink.com. I unticked it but as you can see in the attached Excel graph for today from 0000-0800 ET, WD gusts are still lower than WeatherLink. For the 8-hour period, the WL average gust was 5.5 mph and WD was 3.1 mph (40% lower) while the max WL gust was 14 mph and WD was 11 mph (25% lower).

Any other suggestions for something I might have set incorrectly in WD?
