It's way less than 20%, once you discount spiders and such. Also being framed will not affect your Google indexing in any way.

One note about that JS framebusting... It can prevent your site from being accessed via online translators. Very user-unfriendly. With these Javascript snippets you can explicitly exclude some domain names from being "busted" out of, and I recommend you do.
