I'm not trying to denigrate their work or assert that it's not valuable research. My point is that the discoverability and information accessibility is very very low here, which is what leads to the frustration whenever this site gets posted.
The research is very likely under peer-review so it is very likely that the site will be revised once the paper is accepted and presented at a conference. Just everyone else, people in academic have more stuff to do than there are hours in a day. Be kind, please.
