Multiple LInks from the same domain - how much benefit do they give?

[performagen]

I'm wondering how much added benefit there is to gaining multiple links from the same domain? For example when looking at a competitor in open site explorer I see they have 239 linking domains but 5,066 links. How much additional benefit are they getting over just having 239 links from 239 domains? Also how many links is an optimal number from a domain in that case before there become no more point seeking links from that domain? 5? 10? Thanks

We received a few dozen links on a PR7 page.  Each of those links went to a different page on our website and each of those pages shot up the SERPs almost immediately - and held that new ranking.  So, multiple links on a single domain - or even on a single page can be very beneficial - if they hit different URLs on your website.

However, footer links and blogroll links, all hitting the same URL on your website are known to deliver a fraction of the value compared to the same number of links on different domains.
