Inaccurate article on one point - they say that in 2014 it was proved the smallest number of moves to solve is 26... but in 2010 it was proven to be 20 moves actually. [1]. (And the article they linked to was from 2008 anyway and said that 25 moves was the max needed as of 2008 best knowledge) They probably were referring to the "quarter turn metric" which is 26 quarter-turn moves, but "moves" in speedcubing almost always refers to face turns. And this is made more confusing by the article since the article they linked to was regarding face turns as well. Both of course are mentioned at cube20.org [2]...
