I didn't notice the scale of the X axis at first, it seems like the difference between measurements is not that great.

  It's not that great. But it's the difference between "in accordance with the best theory" and "suggestive of unknown physics". Any unknown physics is likely to be a very small effect, at least numerically. That small effect could require a radical change in the understanding of physics -- like the tiny, hard-to-measure difference between Newtonian gravity and general relativity. Unfortunately, it's yet another case where a small apparent effect turned out to be just noise rather than an actual novelty.
