I don't think it's in the numbers, but in the quality. I do have more than ten to various pages in my website - and that doesn't stop people from deleting some of the links I add to pages, and leaving in others. Though of course if some editor decides your website is absolute rubbish, they may hunt up all links to that website and delete them in one go. But I do think that is only likely to happen when the website is generally poor in content (sorry).
