maximum links in article for good approval percentage?

what is the maximum links in article for good approval percentage?

For me personally, I'll never go above 3 but I really like to keep it around 1 or 2. 

That's just how I do it but others might have a different method.

is this 3 including the way Sven puts two possible links in the auto anchor text .dat file or does it exclude those that say http://domain.com......... which could turn into a possible link but may not.
