- I made a typo... I was looking for wind readings > 51 mph not 47.
Now, it compares to averages if it is > 30 mph. If the average over the
past 10 minutes is < 10 mph, then the reading is assumed to be bogus.
This should handle most situations.
If you have a better idea of how to detect and correc bad readings
(wind speed or otherwise), let me know.
