I'd go with your first instinct, and don't over-analyze your decision. Social psychology studies have shown that people, when given choices, are usually happiest with their first instinct and when they don't over-analyze their decision before making it. I made my rank list a while ago, and I haven't moved anything around since then, but I have checked many times just to make sure that it was still certified (in a similar manner that someone with OCD drives back to his house several times to make sure that the stove is still off). Hmm, sounds like something that I will do right now again as a matter of fact. 😉
