@jeremyshultz I think ultimately, the more localized the better.
One word of caution is that our systems are only as good as the data being fed into them.
So, if you opt-in for a PWS, and you are using our new flex schedules being rolled out next month which rely heavily on evapotranspiration (ET) data (min/max temps, humidity, wind, solar radiation), just be aware that the data from that PWS will be used for calculating ET.
I'm actually still debating if we do allow PWS for ET data. One example is we have a PWS at our office, and last week it was reporting 20 degrees warmer than the actual outside temperature because of its placement.
I'm pretty sure we will be using PWS for individualized ET data (if a user has opted in) since it will be too hard to mix/match weather data.
Hope that helps and didn't add more confusion.
