Summary:
"With six out of ten (or 60%) of articles available in fulltext through Unpaywall, this admittedly small sample is nevertheless consistent with the extension’s estimated range of fulltext availability—65-85% of articles, depending on their topic and year of publication (Unpaywall FAQ, How often does Unpaywall find full text? http://unpaywall.org/faq)"
