Adding a tag analysis would be good
This is good information. But I wouldn’t focus on recommends. Medium itself has discussed problems with both the word “recommends” and the heart shaped logo. It might correlate better with the number of comments. One thing I would like to ask. Republish your post with a slightly different title, “What makes an article popular on Medium? We analyzed 10,000+ data points to find out — REFERENCE” and publish it with the tag “Reference”. I’m trying to build up a reference section for Medium.
