Just came here to say:
I've started to read the paper (thanks to the downloadable PDF, the web version is not accessible apparently for me)
Starting at page 8 (total) or page 6 (as written in the footer), there's horrible graphs, even if you zoom in, they're all blurry and partially unreadable
I'm legit surprised we let research articles be published with poorly designed graphs using poor definition/resolution :')
