The miracle happened in double volume, because Spike Chunsoft released in the West not only Robotics; Notes, but also the continuation of Robotics Notes DaSH. As for the first, you may notice it has the Elite prefix, but this is not the same as Steins Gate Elite a reissue in which the text was cut and the illustrations were replaced with scenes from the anime this version differs from the original with better character models and corrections in the text, which should improve the pace of the story and its perception in general.
