No, I will try this again. Being off by 1 or 2 % is likely, being off by 13% is not. Is that easier?
If you end up being dead going with the majority of doctors, I'd say your formula doesn't work out so well. But you certainly think like a doctor. The first five were pissed that I wanted another opinion. After all, they all agreed and they had learned your formula for being right. I saw one of those doctors after my brain surgery. He felt a wee bit foolish.
