On a monthly basis, "Links to Your Site" in GWT is updated twice or thrice. What I've been noticing over the past few months is that it somehow seems to coincide with a refresh in search engine rank (usually positively) for my website. And whenever I add in more links than usual, this section in GWT seems to take longer to update. So what I'm wondering is, is there really a correlation between GWT "Links to Your Site" and a refresh of search rank? Or is this pattern I'm seeing due to sheer coincidence?
