I'll say it once more - it's not worth it.

Your aim should be at about 70% code coverage - as long as you know in your hearts heart that all has been tested that should have been tested.

What's vitally important (and which is the whole reason why I run coverage tools in the first place), is not the warm, fuzzy feeling I get in my tummy when I see a high number - it's the easy identification of untested code and pathways that yield value in this regard.
