Not sure what you're getting at really? Alert history for just emerald seems mostly NC at least since yesterday or last few days seems VS had a good time then it stopped. So probably just the variance in whoever is logged in and all. If you're talking OUTSIDE of alerts..thats just population screwiness most likely in general.
Just FYI when looking at that data only "Prime" is really legit. That's when you have 33/33/33 in minimal off continent shenanigans
