Looking at the paper, their "10 to 20%" figure is based off of three studies, one for call center employees, one for Indian data-entry workers, and one for Indian IT professionals. The one closest to most of HN's audience is the IT professionals case, and even in that one they note "measured performance among these workers remained constant while remote." In addition, they only mention how "productivity" is being assessed for the call center case (call volumes), not the other two. Personally, I wouldn't really call this "hard data."
