When you say, "ranks pine at the top," that ignores that there are multiple species of pine listed, and that the "top" ranking that you mention is for pitch pine by weight, not by volume. Pitch pine is a very poor wood for home heating, as it produces a lot of creosote (or pitch), and is thus dangerous. Pitch pine was one of the most abundant trees in the area where I lived in eastern Kentucky, but no one burned it for home heating. David

So, the difference is a full 0.2% in energy per pound.
