But, there is another issue which is more subtle and less clear.
I have evidence that PR is not fully passed to to the linked page. It appears as though only half the PR that you would pass from a non targeted link is passed to the targetted link.
If true, this makes links from sites that use the target parameter much less valuable. And, it is a way to link to others, but have less PR "bleed".
This makes some sense considering the theory of operation of PR and the fact that both the original and linked to page are now viewed.
Can anybody confirm or deny this?

I can neither confirm nor deny based on facts. All in all I don't even care much about PR.
As a rule of thumb I use target="_blank" to all external links (to other sites) and never use it with internal links.

Which evidence are you talking about? Keep in mind that the TPR is rather bogus anyway, and you can't determine the RPR (real PR) used internally by Google. A link from a TPR(X) page sometimes make the linked page TPR(X-1), sometimes TPR(X) (though never a TPR(X+1) :). It's also depending on other factors like other outgoing links.
so if i have all my links with _blank, google will count it as out links
Who said this?
The problem with your question is that no one really can proof anything. This is inherent to SEO, unless you make experiments under hard constraints and post the results.
Nearly All you can read on WW is "educated guesses".
So maybe you should try the version out you think is suitable, meaning gives your visitors the best usage experience of your site.
IMHO the use of target does NOT give less weight to a link (why should it?) but I just can't proof it.
