I guess it would depend on what page you have multiple links to. If it is something like a contact page then it may not really matter as that wouldn't usually be a well ranking page. If it were a content page that ranks then I would just leave it.
If it was absolutely necessary to track it all then I would only have a single link to it on any given page and then you could test it's location individually. Test it in the topnav for a period then test over a period of the same length in the footer to decide which location gets better clicks.
