Wind sensor entities need better processing?

Noticed something interesting when we had a power blackout in our area for about 30 minutes: When the HA server came back online the Wind Sensor (identified as MA10660) recorded pretty high spikes for the wind values while in reality there was no change in weather during that time.

The official app does not show a spike like that, so there must be some difference in the way this integration and the MA servers interpret the received data? Does the integration ”deposit” the change in data, what I guess is a number of sensor revolutions, for the single moment of time when the latest value is received, instead of dividing it by the amount of time since the last value received?

For what it’s worth, my HA server is behind an UPS while the gateway is not, so in my case HA remained powered for some 15 min longer than the gateway did. Maybe this progression of time in HA might affect how derivatives like speeds are calculated?
