Just look at some of the countries at the top of the index and you'll realize that reciprocity is far from the deciding factor. Americans can go to many countries (even ones without a large tourism economy) despite being rather stingy with letting others in. Far more important is assessing the likelihood that someone will try to permanently stay/work on a tourist visa.
