Your just restating (or not understanding) what I said, the average is misleading because its seasonal, which isn't even clear unless you look for it in the graphs (because they swing). edit: (and I should be clear, its still swinging when the daily average is 5%, it might say produce 8% during the evening but only 2% during the day).
Here look at whats going on:

You will have to tweak the graph because I didn't spend the time to figure out how to create a link to a graph which isolates just wind, and then expands the time-frame out to an entire year.
If you do that, what you see is during the summer the lulls are much lower and last for much longer. AKA it might go for a week or two basically not producing anything. It happens at other times of the year too, but during the spring/fall the weather is changing faster (aka its less stable) and the running average goes up.
This is what the wind/solar people seem to refuse to understand, its not a simple averaged calculation over a year because the worse case is much much worse for storage and capacity. The wind blows at 5% nameplate for two weeks, and the amount of storage and overbuild required to bridge that makes it an order of magnitude more expensive than pretty much every other source. Made massively worse because in say TX, that is also when energy consumption peaks.
