Not the point

I realize that it's also not the point. There's a strong correlation between zone and heating degree days. It simplifies the language to understand/use that correlation. However, the point is something's wrong with that map, and thus I wouldn't take it to mean very much. Even disregarding the muddy waters you're stirring up with the zone correlation/discussion, they use state boundaries all over the map, perhaps they think the cumberland plateau has seceded.
