Some explanation on what we currently display:
SKY takes an instantaneous observation every 3sec (or 15sec in power save mode). Captures speed and direction.
1min Wind Average = sum of the obs over the last 60seconds divided by number of obs. Same logic for 5min, 30min, 3hr, 1day per Data archive buckets explained
1min Wind gust = the highest single ob over the last 60sec.
1min Wind lull = the lowest single ob over the last 60sec.
Curious to hear thoughts on labeling these values. “Gust / Lull” vs. “Max / Min” ? Remember, the default dashboard display data is purposefully simple intended for the average home owner, not the professional meteorologist. Home owner: “wow, it was super windy today. I wonder how windy it was to blow over my pool umbrella?” 
For the professional meteorologists and serious weather gurus like you gals / guys … remember to keep the target audience in perspective. And should you desire custom derived data (like an alternative definition of gust), we absolutely encourage data manipulation by API or third party application!
