Using HadCRUT when BEST is demonstrably superior isn't per se «wrong» so much as indicative of poor judgement or possibly cherry picking for an agenda; especially this is so when one has so many datasets available and instead of treating each one separately and distinctly and attempting to confirm one's hypothesis on just one of them at a time and commenting on differences among them, one stitches together exactly the pieces one can force into a persuasive but meaningless shape in what can only be viewed as a spoof of graphical analysis.
