I cannot help but consluding that BEST had a goal in mind , or more likely their algorithm was designed to make all trends rise from past to present. If the real trend wouldn't cooperate (like Alabama) they cooled the past and warmed the present. If the real trend was in the right direction, they just pretended to adjust the data.
