the EBU tends to choose entries that won't stand a chance eventually (remember Iceland performing after Denmark 2013, Lithuania and Germany performing after Austria 2014, Switzerland and Cyprus performing after Sweden 2015..). Some will think it's just the result of mixing different genres well, I think they use some so-called "hopeless" entries to make others stand out even more. And somehow, it sounds logical: were you responsible for the draw, would you put all the favourites one after the other?
Of course, I have no proof - that you seem so eager to find - but so far nothing makes me think my assumption is untrue either.
