Your conclusion about Google/Fast pretty much sums up my approach as well. Most of my rankings compare quite well between Google and Fast. However, I still find some major differences. As a quick example I ranked 4 for a term in Google and only 208 in Fast. This gives me a bit of incentive to explore the differences between the Fast and Google algorithms.
