Ahh, so, turns out some of the colors in a few of the 
charts (including Figure 13) were transposed (that's what I
get for just looking at the numbers in the draft), making 
several of the findings seem a bit strange.  This has since 
been corrected and should clarify your cocnern..

Thanks Pekka (and several others) for pointing this out.
