Average speed graph values are integers only
I have a Davis VP2 set to log at 1 minute interval. Cumulus has the same logging interval. I don't have "Calculate 10 min wind average" set, so I assume the value is passed through as an integer. Is this the case? I ask, because the wind speed graph always looks very "artificial".

Re: Average speed graph values are integers only
Having posted the above, I just saw an average speed of 14.9 knots on the Cumulus display, so I assume the values aren't being passed as integers, and some rounding is occurring in Cumulus?

Re: Average speed graph values are integers only
Yes, Davis stations supply wind speeds to whole numbers of mph. The Davis DLL does any required conversions to other units; I'm not sure whether it rounds those.
