I have somewhere near 75,000 links in Wikipedia

Are you sure about this? Unless you're counting links from old versions of Wikipedia pages. Many Wikipedia pages have thousands of previous versions, which you can see by looking at the history of previous edits. If your site got a backlink from a wikipedia page say five years ago, then (assuming it has never been deleted) that link appears on all the subsequent page revisions. But even if it appears on 5000 previous versions of the page, it's basically the same link.
