So are you saying too much variation in external and/or internal could cause a penalty ?
IMO, anchor text for internal links is not being scored currently. Internal links just count for flow of PR but not flow of anchor text.This I think is one big change they did around Panda time last year. Either this could be part of panda or a separate change. But big changes related to links were mentioned by a google employee on a popular forum and my guess is this is one of those changes then.
So it all boils down to anchor text flow via external links. Google does use other text on the linking page and not just the anchor text for determining this flow. However, with penguin, they seem to have introduced an algorithmic penalty based on anchor text used. It might be based on over use of same keywords or diversity in keywords used as anchor text.But my argument is that overuse of same keywords (from multiple domains) is a natural one as long as the keywords are present in title or h1.But google engineers might not necessarily be thinking like I do.
