I feel that I should make three points before I reveal my findings:

1. My method included watching every episode. Not all 80 hours, but the Signature challenge judgment of each episode, as that is when the handshake is given. This changed in the most recent series. (Trust me, it's madness.)

2. If you are thinking, Scott, investigating this is a massive waste of time, may I respond with this: And here we are — you clicked on the article.

3. And if you are wondering whether I got paid for writing this article: I did.
