While interesting, this does not seem very convincing to me. They successfully show that Niemann was playing many games with a high percentage of "engine perfect" moves, but they do not do enough to show that this is inconsistent with what top players usually do. A whole distribution of scores is shown for Niemann but only limited summary statistics are shown for other top players. A proper comparison would involve showing the same type of data for both.
